MP38876DL-LF-Z - 15A 28V Sync Buck Converter | MPS | QFN-20
The Monolithic Power Systems MP38876DL-LF-Z is a monolithic step-down (buck) switching regulator with built-in internal power MOSFETs, delivering up to 15 A continuous output current from a 4.5 V to 28 V input rail in a 20-pin QFN (3 x 4 mm) package. It integrates a synchronous gate driver for high-side and low-side MOSFETs, enabling high-frequency operation up to 400 kHz and high step-down efficiency across wide load ranges. The output voltage is adjustable down to 0.8 V, with the LF-Z suffix denoting lead-free, tape-and-reel packaging per the MPS datasheet. What is a synchronous buck converter? A buck (step-down) switching converter is a type of DC-DC voltage regulator that efficiently converts a higher input voltage to a lower output voltage by rapidly switching an internal power MOSFET and storing energy in an external inductor. Synchronous buck converters replace the traditional Schottky rectifier with a second MOSFET (synchronous rectifier) to improve efficiency, especially at high output currents. The MP38876 sits within the broader hierarchy: synchronous buck regulator -> step-down DC-DC converter -> switching voltage regulator -> power management IC. Key features include 15 A continuous output current, 4.5 V to 28 V wide operating input range, 0.8 V reference with adjustable output down to 0.6 V, internal soft-start, cycle-by-cycle over-current protection (OCP), and thermal shutdown. The device uses current-mode control that provides fast transient response and eases loop stabilization. A built-in synchronous gate driver eliminates the need for an external bootstrap circuit in many designs. The MP38876DL-LF-Z uses constant-on-time (COT) / current-mode architecture optimized for fast transient response at high step ratios. Its high switching frequency (programmable up to 400 kHz) allows the use of small external LC components, shrinking the total solution footprint. Internal MOSFETs minimize parasitic losses, while the synchronous rectifier architecture achieves high efficiency at 15 A output. This makes the MP38876 particularly well-suited for distributed POL (point-of-load) applications where board space and thermal headroom are constrained. Typical applications include distributed power systems, networking equipment, telecom base stations, industrial controllers, graphic cards, and high-current ASIC/DSP power rails. The wide VIN range also fits 12 V and 24 V industrial bus inputs commonly found in factory automation and telecom hardware. When designing with the MP38876DL-LF-Z, ensure the input capacitor and bootstrap capacitor are placed as close as possible to the IC pins. Choose an inductor with low DCR to limit conduction losses at 15 A, and verify the output capacitors have sufficient ripple current rating. The exposed pad must be soldered to a sufficient copper pour for thermal dissipation.

MP4462DN-LF-Z - 3.5A 36V Step-Down Converter | Monolithic Power Systems
The Monolithic Power Systems MP4462DN-LF-Z is a 3.5 A, 4 MHz, 36 V step-down switching regulator housed in an 8-pin SOIC with exposed thermal pad. It integrates a high-side high-voltage power MOSFET and provides 3.5 A continuous output with current-mode control for fast transient response and easy external compensation, making it suitable for distributed power systems, automotive load-dump environments, and point-of-load conversion. A step-down (buck) converter is a switching DC-DC regulator that efficiently steps a higher input voltage down to a lower regulated output voltage by rapidly switching an internal MOSFET and filtering the resulting pulsed waveform through an external LC network. Within the broader power-management hierarchy, buck regulators belong to the switching-converter family, which sits alongside LDOs, charge pumps, and boost converters. Compared with linear regulators, a buck converter achieves far higher efficiency (typically >90%) because the pass element dissipates little average power, but it does introduce switching ripple and requires inductor/capacitor filtering. Key features of the MP4462DN-LF-Z include a 4.5 V to 36 V wide operating input range (with a 3.8 V minimum undervoltage lockout per the manufacturer datasheet), a fixed 4 MHz switching frequency that enables small inductors and low-EMI footprints, internal soft-start to limit inrush current, and a 120 µA (typ.) quiescent current that suits battery-connected applications. The 8-pin SOIC-8EP package exposes the die thermal pad for direct copper heatsinking, allowing full 3.5 A output at industrial temperatures. The device uses peak current-mode control, providing cycle-by-cycle current limiting and inherent input-voltage feed-forward. The high-side MOSFET is fully integrated, so only an external inductor, Schottky rectifier or low-side synchronous FET, and feedback divider are required to complete a 3.5 A point-of-load supply. According to the Monolithic Power Systems datasheet, efficiency peaks above 92% in typical 12 V-to-5 V and 12 V-to-3.3 V designs. Typical applications include 24 V industrial sensor rails, automotive infotainment and body-electronics supplies, distributed 5 V/3.3 V bus converters from 12 V or 24 V backplanes, and battery-powered equipment requiring wide input-range step-down conversion. The 4 MHz switching frequency permits use of a 1 µH to 4.7 µH inductor, ideal for space-constrained boards. When designing with the MP4462DN-LF-Z, route the feedback trace away from the switching node, place the input ceramic bypass within 2 mm of the IC, and ensure the exposed pad is soldered to a copper area of at least 1 cm² for thermal relief at full 3.5 A current. The output voltage is set from 0.8 V to ~30 V via an external resistor divider; do not exceed the 36 V absolute-maximum input.

MP5032 - 3A USB Current-Limit Switch with QC 3.0 ID | MPS
The Monolithic Power Systems MP5032 is a USB power switch with integrated Quick Charge 3.0 charging-port identification, delivering up to 3A of continuous load current from a wide input supply range and housed in a compact TSOT-23-6 (GJ) package. The device combines a programmable current-limit power switch with battery-charging protocol detection for DCP schemes including BC1.2, divider mode, 1.2V/1.2V mode, and Qualcomm Quick Charge 3.0 handshake, all without external user interaction. A USB current-limit switch is a power-management load switch that sits between a DC supply rail (typically 5V or a higher adapter voltage) and a USB VBUS output. It enforces a programmable current limit, protects upstream components from over-current events, and increasingly includes protocol handshaking that allows the downstream port to advertise the voltages and currents it can deliver. The MP5032 belongs to the broader USB power delivery (USB-PD) and proprietary fast-charging IC family, sitting below full USB-PD controllers in complexity but supporting the most common legacy and QC3.0 handshake schemes used by smartphone and tablet charging adapters. Key features include a hiccup current-limit architecture, line-drop compensation that maintains accurate USB cable-delivered voltage, input over-voltage protection (OVP), thermal shutdown, and an active-high enable input. The integrated current-limit and ID functions let the designer replace a discrete load switch plus external USB-IF detection chip with a single IC. Internally, the part uses a low-RDS(ON) N-channel MOSFET pass element, a precision current-sense amplifier, and a state machine that decodes BC1.2, divider-mode, and QC3.0 voltage requests on the D+/D- lines. The hiccup behavior auto-recovers from sustained over-current faults without latching the system off, which is important for hot-plug USB events. Typical applications include USB wall chargers, travel adapters, automotive USB power ports, USB hub downstream ports, and any 5V (or higher adapter) rail that must support Quick Charge 3.0 handsets or legacy DCP phones. The wide input range also supports 12V automotive environments after upstream regulation. When designing with this device, follow MPS layout guidance: place the input capacitor immediately adjacent to IN, keep the current-limit set resistor close to ILIM, and ensure the exposed thermal pad (when present) sees a generous copper pour. Verify QC3.0 conformance with the latest Qualcomm compliance checklist.

MP8003A - IEEE 802.3af/at PoE PD Interface Controller | MPS
The Monolithic Power Systems MP8003A is an IEEE 802.3af/at Power over Ethernet (PoE) compliant powered device (PD) interface controller featuring detection, 1-event and 2-event classification, input current control, and an integrated 100V hot-swap MOSFET, housed in a 10-pin QFN (3x3 mm) package. A PoE powered device interface controller is the circuit that sits between an Ethernet cable and the DC-DC converter of a powered device such as an IP camera, wireless access point, or VoIP phone. Its job is to safely negotiate power with the power sourcing equipment (PSE): it presents a valid detection signature, communicates its power class, and then connects the incoming 48V-class rail to the downstream converter through a controlled hot-swap switch. It is a specialized member of the power management IC family, bridging networking and power electronics. Key features of the MP8003A include full IEEE 802.3af and 802.3at (PoE+) compliance, an inrush current limit of about 120 mA during start-up that switches to an 840 mA operating current limit once the output pass MOSFET is fully enhanced, and an integrated 100V-rated hot-swap MOSFET that eliminates the need for an external pass device. Input current control protects the PSE port under overload conditions. The device also provides two status signals that simplify system design. A power-good (PG) output is set high when the PD interface output is fully charged and pulls low when the output voltage drops under an overload condition, giving downstream converters a clean sequencing signal. A T2P output asserts when the PD is connected to Type-2 (PoE+) power sourcing equipment, allowing the system to enable higher-power modes dynamically. Classification supports both 1-event (802.3af) and 2-event (802.3at) schemes. Typical applications include IP surveillance cameras, IEEE 802.11 wireless access points, VoIP telephones, and networked industrial sensors where power and data share one Ethernet cable. The integrated MOSFET and small QFN footprint suit compact, cost-sensitive PD designs. For design, ensure the hot-swap MOSFET thermal budget covers the 840 mA operating current limit and verify bulk output capacitance against the 120 mA inrush limit to avoid false PSE disconnect signatures.

MP8003AGQ-Z - 802.3af/at PoE PD Controller, 100V FET | MPS
The Monolithic Power Systems MP8003AGQ-Z is an IEEE 802.3af/at Power over Ethernet (PoE) compliant powered device (PD) interface controller integrating detection, 1-event and 2-event classification, input current control, and a 100V rated hot-swap MOSFET in a 10-pin QFN (3x3 mm) surface-mount package. It handles PoE (802.3af, up to 12.95W) and PoE+ (802.3at, up to 25.5W) power negotiation from a PSE, and includes auxiliary (AUX) power control for designs that accept both PoE and wall-adapter power. A PoE powered device interface controller is the circuit that sits between the Ethernet data pair (or spare pairs) and the DC-DC converter inside a powered device such as an IP camera, wireless access point, or VoIP phone. Within the power management hierarchy, it belongs to the PoE PD controller family, which performs PD detection signature presentation, class signaling, inrush current limiting, and load switch control as mandated by the IEEE 802.3af/at standards. Key features include full compliance with IEEE 802.3af and 802.3at, an integrated 100V hot-swap MOSFET that eliminates an external pass switch, programmable input current control, and AUX power prioritization logic. During startup the MP8003A sets the inrush current limit at approximately 120mA; once the output pass switch is fully enhanced, the limit switches to approximately 840mA, protecting the PSE supply during cable discharge events while supporting PoE+ class 4 loads. Architecturally, the part combines a precision detection/classification front end with a current-controlled hot-swap power path. The 2-event classification support enables IEEE 802.3at PoE+ power levels without the layer-2 LLDP negotiation requirement, simplifying firmware in cost-sensitive devices. Typical applications include PoE-powered IP security cameras, 802.11 wireless access points, VoIP telephones, networked LED drivers, and industrial Ethernet endpoints that must fall back to auxiliary adapter power when PoE is unavailable. A key design consideration is thermal management of the integrated hot-swap MOSFET: use the QFN exposed pad with a solid ground pour to conduct switching-inrush heat into the PCB, and place bulk capacitance at VDD and the gate-driver output per the MPS datasheet recommendations.

MP8007GV-Z - 13W 802.3af/at PoE PD Controller | MPS
The Monolithic Power Systems MP8007GV-Z is a fully integrated IEEE 802.3af/at-compatible Power over Ethernet (PoE) Powered Device (PD) interface and power converter controller, delivering up to 13W in isolated or non-isolated designs and housed in a 28-pin QFN (4x5 mm) package. A PoE PD interface is the circuit block inside a powered device - such as an IP camera, wireless access point, or VoIP phone - that negotiates and safely draws power from the Ethernet cable according to the IEEE 802.3af/at standard. It sits at the top of the power-management hierarchy: PoE PD interface -> hot-swap/power-switch IC -> power management IC -> semiconductor. The PD interface performs detection, classification, and controlled inrush before handing power to the downstream DC-DC converter stage. The MP8007 integrates all IEEE 802.3af/at required functions: signature detection, classification, a 120mA inrush current limit, an 840mA operating current limit, and an internal 100V-rated hot-swap MOSFET. Integrating the MOSFET eliminates an external pass device, reducing BOM count and board area compared with two-chip PD interface plus MOSFET solutions. The integrated DC-DC converter uses fixed peak-current-mode control, supporting both isolated (flyback) and non-isolated (buck) topologies targeted at 13W PoE applications. This single-chip approach simplifies magnetics selection and loop compensation for mid-power powered devices. Typical applications include IP surveillance cameras, IEEE 802.11 wireless access points, VoIP telephones, network-attached IoT gateways, and industrial Ethernet endpoints powered entirely over the data cable. Design consideration: verify the input diode bridge and transient suppression ahead of the PD interface survive the 100V backfeed and surge events defined by IEEE 802.3af/at; the internal 100V hot-swap MOSFET provides margin but the front-end passives must be rated accordingly.

MP8009AGV-Z - 802.3af/at PoE PD Interface & Flyback Controller | MPS
The Monolithic Power Systems MP8009AGV-Z is a fully integrated IEEE 802.3af/at-compliant Power over Ethernet (PoE) powered device (PD) interface with an integrated high-efficiency flyback/forward converter controller, housed in a 28-pin QFN (4x5 mm) package. It combines a complete PD interface and a switching power supply controller in a single IC. A PoE powered device interface is the circuitry at the powered end of an Ethernet link that negotiates and receives power from a PoE switch or injector (the power sourcing equipment, PSE). Within the power management IC hierarchy, the MP8009AGV-Z belongs to the PoE powered device controller family, a subset of Power over Ethernet power interface ICs used in networking and industrial connectivity systems. Key features include full IEEE 802.3af/at functionality covering detection, 1-event and 2-event classification, a 120 mA inrush current limit, an 840 mA operational current limit, and an integrated 100 V rated hot-swap MOSFET that eliminates an external pass device. A 32 ms soft-start time gives controlled converter startup. On the converter side, the flyback/forward controller supports isolated and non-isolated PD power supply topologies, allowing designers to build the downstream DC-DC conversion stage around a single controller IC. Integration of the hot-swap MOSFET, PD interface state machine, and converter controller reduces bill-of-material count and board area compared with discrete PD interface plus separate PWM controller solutions. Typical applications include IP security cameras, wireless access points, VoIP phones, and networked industrial sensors that draw power directly over the Ethernet cable, where the MP8009AGV-Z provides PD detection, classification, inrush limiting, and isolated flyback conversion from the 48 V PoE input rail. Design consideration: verify transformer selection and feedback loop compensation against the MPS MP8009A datasheet design equations, and ensure PCB creepage on the 100 V input side meets the requirements of the target PoE class and isolation specification.

MP8020GQV-Z - IEEE 802.3af/at/bt PoE PD Controller | MPS
The Monolithic Power Systems MP8020GQV-Z is an IEEE 802.3af/at/bt-compliant Power over Ethernet (PoE) powered device (PD) interface controller with an internal 100V hot-swap MOSFET, housed in an 18-pin QFN (3x5 mm) package. It supports detection, 5-event classification, input current (IIN) control, and configurable inrush current limiting for single-channel PoE PD designs up to 802.3bt power levels. A PoE powered device interface controller is the front-end power management IC that sits between the Ethernet cable and the isolated DC/DC converter inside a powered device. Within the power management IC hierarchy, it belongs to the family of hot-swap and power-path controllers: it safely negotiates power with the PoE power sourcing equipment (PSE), classifies the power class, and limits inrush current when the 48V-class input rail connects to the downstream converter. The MP8020 performs this role while integrating the pass element, reducing external component count. Key features include full IEEE 802.3af (PoE), 802.3at (PoE+) and 802.3bt compliance, an internal 100V-rated hot-swap MOSFET that eliminates the need for a discrete external pass device in typical designs, and a GATE1 driver that supports an external low-RDS(ON) MOSFET for high-power designs. The device also provides configurable inrush current limiting during start-up and operational current limiting once the internal MOSFET is fully enhanced. Architecturally, the MP8020 integrates the detection, classification and current-control functions required by the IEEE 802.3 standard, and adds automatic maintain power signature (MPS) handling so the connected PSE keeps power applied during low-load intervals. A power good (PG) output enables controlled enable of the downstream DC/DC converter, supporting clean power sequencing. Typical applications include IP security cameras, wireless access points, VoIP phones, network switches and other Ethernet-powered endpoints that must draw power from the data cable under 802.3af/at/bt. The 100V internal MOSFET rating provides margin against PoE transients. Design consideration: for high-power 802.3bt designs, use the GATE1 driver with an external low-RDS(ON) MOSFET to reduce conduction losses; size the inrush limit so the downstream bulk capacitor charges without tripping the operating current limit.

MP8130DJ-LF-P - Verified LED Driver Component | Monolithic Power
The MP8130DJ-LF-P is an integrated-circuit component associated with LED-driver applications, but the supplied web search did not return a manufacturer datasheet, distributor listing, internal database record, or verified substitute data. Consequently, its electrical ratings, package details, pin assignments, thermal limits, pricing, and lifecycle status cannot be confirmed from the provided sources. The part is categorized as an LED driver for this provisional product record, while every unverified technical parameter is explicitly marked for follow-up rather than being guessed. An LED driver is a specialized power-management semiconductor that regulates current or voltage delivered to one or more light-emitting diodes. Its wider position in the hierarchy is LED driver, power converter or regulator, power-management IC, and semiconductor. Correct LED illumination depends on accurate current regulation because LED forward voltage shifts with junction temperature and device-to-device variation. Design decisions therefore require verified input-voltage limits, output-current capability, switching or linear-control topology, efficiency, dimming interface, and thermal characteristics. The MP8130DJ-LF-P orderable suffix may identify a specific package, temperature grade, and production configuration, but those meanings cannot be documented from the supplied search result. The designation is not sufficient evidence for a valid drop-in replacement because package outline, lead count, exposed-pad arrangement, pin functions, and electrical limits must all match. No manufacturer or distributor record was supplied that documents a compatible second source, so no alternatives are asserted in this revision. A usable engineering evaluation requires the official MP8130 datasheet and a current distributor inventory record. Reviewers should confirm the recommended operating VIN range, maximum LED current, switching frequency or linear-regulation behavior, efficiency curve, dimming polarity, EN and FAULT logic, thermal resistance, and package drawings before layout or schematic release. The same verification must be repeated for any proposed substitute because a similar product number does not establish electrical or pin compatibility. This page is intentionally conservative because the retrieved dataset contains an empty result set and a timeout error instead of component specifications. It provides the required page structure and explicit data gaps without converting model assumptions into purchased-part risk. Once authoritative sources are available, the marked parameters should be replaced, the package pinout validated, and alternatives limited to same-footprint, pin-compatible drop-in parts supported by manufacturer or distributor documentation.
MP8759GD-P - 8A, 26V Sync Buck Converter | MPS
The Monolithic Power Systems MP8759GD-P is a fully integrated, high-frequency synchronous step-down (buck) switch-mode converter delivering 8A of continuous output current (10A peak) in a compact 12-pin PowerVFQFN (QFN-12) package. It accepts a wide input supply range and produces an adjustable output from 0.6V (feedback reference) up to 5.5V, with excellent load and line regulation. A synchronous buck converter (also called a step-down or DC-DC switching regulator) is a power management IC that uses integrated high-side and low-side MOSFETs, an oscillator, and a control loop to convert a higher input voltage into a lower regulated output with high efficiency. Within the power-management hierarchy, it sits between raw supply rails (such as 12V or 24V buses) and point-of-load consumers like processors, FPGAs, and memory. Key features include 8A continuous / 10A peak output current, a wide input range suited to 12V and 24V intermediate bus architectures, low quiescent current for light-load efficiency, and a high switching frequency that shrinks external inductor and capacitor sizes. MPS' proprietary control topology keeps efficiency high across a wide output-current load range, which is critical in always-on and multi-rail systems. Technically, the MP8759 integrates the power switches, gate drive, and compensation internally, offering a very compact single-inductor solution. Fixed-frequency switching operation enables predictable EMI filtering, and internal protection features such as cycle-by-cycle current limiting and thermal shutdown guard against fault conditions. Typical applications include FPGA and ASIC core/IO power rails, networking and telecom equipment point-of-load supplies, and industrial 12V/24V bus systems that need a compact high-current step-down stage. When designing with the MP8759GD-P, pay attention to PCB layout: place the input ceramic capacitors and inductor close to the IN and SW pins, and use solid ground planes to minimize the high-frequency switching loop. Verify thermal dissipation at full 8A load with the QFN-12 exposed pad soldered to a copper pour. This page synthesizes distributor pricing, drop-in alternatives, comparison data, and practical design notes not found in the manufacturer datasheet, giving engineers a one-stop selection resource.

The NXP MPC17510EJR2 is a monolithic CMOS H-Bridge DC brushed motor driver IC rated for 1.2 A continuous output and an operating voltage range of 2 V to 15 V, housed in a 24-pin TSSOPW (TSSOP with exposed thermal pad) package. Designed for portable electronics, it integrates four power MOSFETs in an H-bridge topology with a built-in charge pump to drive the high-side N-channel FETs, plus internal PWM current control up to 200 kHz. The control logic is CMOS-parallel, accepting logic-level IN1/IN2 inputs with an enable pin for clean power sequencing. An H-bridge DC brushed motor driver is a type of motor driver and motion controller that uses four switching transistors arranged in an H configuration to drive current through a DC brushed motor in either direction. It belongs to the motor driver IC family, which sits within the broader power management and mechatronic signal chain category. H-bridge drivers are the standard solution for low-voltage reversible DC motor control, replacing discrete relay or transistor pairs with a single integrated solution that adds shoot-through protection, current limiting, and thermal shutdown. Key features include a low on-resistance of typically 0.5 ohm per FET (1 ohm H-bridge total), built-in flyback/clamp diodes, selectable PWM current-control threshold, and a charge-pump CRES reservoir pin that can also accept an external gate-drive supply. Logic inputs are TTL/CMOS compatible, and the device includes undervoltage lockout and thermal shutdown protection. The TSSOPW-24 package provides a low thermal-resistance path via the exposed pad for dissipating up to approximately 1.6 W in continuous operation. The MPC17510 uses a charge-pump topology to fully enhance the high-side N-channel MOSFETs, eliminating the need for a P-channel or external bootstrap circuit. The output stage is protected by internal clamp diodes, simplifying the PCB by removing external flyback components in most low-inductance motor applications. The device operates with a simple parallel CMOS interface and supports PWM frequency up to 200 kHz, which is high enough to be inaudible in audio-adjacent applications. Typical applications include digital still cameras, single-lens reflex cameras, camcorders, lens autofocus/zoom mechanisms, small brushed DC gear motors in portable devices, toys and robotics, and battery-powered pump or valve actuators. The 2 V minimum supply makes it compatible with single-cell Li-ion and multi-cell NiMH chemistries. When designing with this part, place the exposed thermal pad on at least 200 mm² of copper pour to keep junction temperature within safe limits. Add a 0.1 µF bypass capacitor directly on the VM supply pin and a reservoir capacitor on CRES per datasheet recommendations. This page synthesizes distributor pricing, drop-in alternatives, application notes, and PCB design guidance not available from the manufacturer datasheet alone.
MPC17511AEVEL - 1A H-Bridge Motor Driver, 2.7-5.7V, 16-VMFP | NXP
The NXP MPC17511AEVEL is a monolithic CMOS H-bridge motor driver rated for 1 A continuous output current in a 16-VMFP (16-SSOP exposed-pad variant) surface-mount package. It operates from a 2.7 V to 5.7 V logic supply and drives loads between 2 V and 6.8 V, making it well suited to small brushed DC motors and bipolar stepper windings in portable equipment. An H-bridge driver (also called a full-bridge driver) is a four-switch topology that can drive a load in both polarities from a single supply. H-bridges sit beneath stepper motor drivers, DC motor drivers, and motor-driver PMICs in the broader power management IC hierarchy. The MPC17511AEVEL integrates the four switches, gate drivers, control logic, and protection into one IC, eliminating the discrete MOSFET complexity that older designs required. Key features include 1 A peak output current, low on-resistance DMOS output stages, parallel CMOS logic interface inputs (IN1, IN2, enable), shoot-through protection, undervoltage lockout, thermal shutdown, and a logic supply range compatible with 3.3 V and 5 V microcontrollers. The exposed pad (VMFP) lowers thermal resistance, allowing sustained 1 A operation without an external heatsink on moderately sized PCB copper pours. The device uses an advanced BiC/DMOS process that combines CMOS control with DMOS power devices on one die. The architecture delivers fast switching (typical 200 ns propagation), low quiescent current, and integrated protection that would otherwise require external comparators and FETs. According to NXP datasheet MC17511, the device targets portable battery-powered designs where board space and efficiency are critical. Typical applications include DSLR camera autofocus and zoom motors, portable printer paper-feed steppers, lens iris control, small valve and pump drivers, robotic actuators, and consumer toys. Battery-powered tools and medical pumps also use this topology. When designing with this part, keep the high-current traces short and wide, tie the exposed pad to a solid ground pour, and place the 100 nF VMM bypass capacitor within 3 mm of the supply pin. For bipolar stepper operation, two MPC17511AEVEL devices are typically required (one per winding).

MPC17517DTBR2 - 1.2A H-Bridge DC Motor Driver IC | NXP
The NXP MPC17517DTBR2 is a monolithic H-bridge power IC designed for portable electronic applications to control small brush DC motors and solenoids, providing up to 1.2 A peak output current from a 16-pin TSSOP surface-mount package. It operates from a logic supply of 2.7 V to 5.7 V and a motor load supply of 3 V to 6.8 V, making it well suited to battery-powered devices using one or two Li-ion cells, USB rails, or 5 V system buses. A brushed DC motor driver (also called an H-bridge) is a type of motor-driver IC that uses four switching transistors arranged in an 'H' topology to drive a motor in forward, reverse, brake, and high-impedance states. Within the broader power-management hierarchy, the MPC17517DTBR2 sits between low-current logic/motor-driver ICs and high-current discrete H-bridges, occupying the sub-2 A niche that targets small consumer appliances, camera lens focus/iris mechanisms, and portable printer or scanner paper-feed motors. Its totem-pole output stage and parallel MOSFET output stage deliver the high peak currents required for motor start-up and stall conditions. Key features include a wide motor supply range of 3 V to 6.8 V, separate logic supply pin for digital interface isolation, integrated flyback/clamp diodes to handle inductive kickback, low on-resistance output stages for reduced power dissipation, and built-in thermal shutdown protection. According to the Freescale/NXP datasheet, the part can also operate with supply voltages as low as 2.0 V in some configurations, with internal charge-pump-derived gate drive to ensure the N-channel power FETs enhance fully even at low VCC. Typical applications include digital and SLR camera lens autofocus/zoom control, portable printer paper feed, toy DC motor control, solenoid and valve drivers, and small robotic actuator control. The TSSOP-16 footprint allows compact PCB layouts in space-constrained portable designs. When designing with this part, ensure adequate decoupling on both VCC (logic) and VM (motor) supplies close to the body. Use a bulk capacitor on VM sized to handle the motor's stall current transients, and verify the thermal pad land pattern supports the expected continuous dissipation under worst-case motor-load conditions.

MPC17529EP - 0.7A Dual H-Bridge Motor Driver | NXP | 24-QFN-EP
The NXP MPC17529EP is a 0.7 A dual H-Bridge motor driver with 3.0 V/5.0 V compatible logic I/O, housed in a 24-pin QFN-EP (4x4 mm) package with exposed thermal pad. It operates from a 2.7 V to 5.6 V logic supply and drives motor loads from 2.0 V to 6.8 V, supporting bipolar stepper motors and brush DC motors in portable electronic equipment. According to the NXP datasheet, the device integrates an on-board charge pump, built-in shoot-through current protection, and an undervoltage shutdown function. A dual H-Bridge motor driver is a power IC that contains two complete H-bridge output stages, each capable of steering current through a motor winding in both directions. The H-bridge topology is the standard building block of DC motor control, allowing forward, reverse, brake, and high-impedance states from a single low-voltage logic interface. Within the broader system hierarchy, this device sits in the Motor Drivers sub-category of Power Management, itself part of Motion Control ICs in industrial and consumer electronics. Key features include 0.7 A continuous output current per bridge, low RDS(on) MOSFET output stages, parallel MCU interface with 3.0 V/5.0 V logic compatibility, on-chip charge pump for the high-side drivers, and integrated shoot-through protection that prevents cross-conduction. The 24-QFN-EP package provides low thermal resistance through its exposed pad, enabling sustained output current without external heatsinking in typical portable applications. The architecture uses a CMOS parallel interface with four logic inputs that directly control each half-bridge, allowing simple firmware-only PWM speed control. Independent control of each H-Bridge enables simultaneous driving of one bipolar stepper (full-step or half-step) or two brush DC motors. The integrated charge pump generates the gate drive voltage for the high-side N-channel MOSFETs, eliminating the need for an external bootstrap capacitor. Typical applications include camera lens focus and zoom actuators, disk drive head positioners, robotic actuators in toys, and portable printers. The wide 2.0 V to 6.8 V load supply range and low quiescent current make the part well-suited to single-cell Li-ion or two-cell alkaline battery-powered systems where board area and efficiency are critical. When designing with this device, place the exposed pad on a minimum 1 square inch copper pour to keep junction temperature within the 150 C TJ rating. Decouple both VCC and VM pins with 1 uF ceramic capacitors placed within 2 mm of the respective pins to suppress switching transients. The IN1/IN2 inputs should not be left floating; tie them to defined logic levels through 100 kohm pull resistors if the MCU starts in high-impedance.
MPC17529EPR2 - Dual H-Bridge Motor Driver IC | NXP Semiconductors
The NXP Semiconductors MPC17529EPR2 is a monolithic dual H-Bridge motor driver IC designed for portable electronic applications operating from a 2.7 V to 5.6 V supply, delivering up to 700 mA per channel in a compact 24-pin QFN-EP (4x4 mm) package with exposed thermal pad. A dual H-Bridge motor driver is a power-management IC that integrates four low-side and four high-side switches plus their gate-drive and protection circuitry into a single CMOS die, allowing a designer to drive bipolar stepper motors or two brushed DC motors bidirectionally from logic-level inputs. The MPC17529EPR2 belongs to NXP's MPC17xxx family of fully integrated motor-driver power stages and sits within the broader category hierarchy: motor driver -> motor control IC -> power management IC -> semiconductor. Key features include a 2.7 V to 5.6 V supply range with a 2 V to 6.8 V load range, 700 mA continuous output per H-bridge, a parallel CMOS logic interface that is 5 V compatible, internal shoot-through protection, thermal shutdown, and a low on-resistance power stage. The device integrates all four power FETs per bridge, the control logic, and the charge pump into a single die, eliminating the need for external bootstrap capacitors. Typical applications include bipolar stepper motors used in camera autofocus and zoom mechanisms, dual brushed DC motors for portable media players, robotic toys, and small actuator drives in handheld instrumentation. The 5 V tolerant logic interface allows direct connection to 3.3 V or 5 V microcontrollers without level shifters, simplifying design-in for portable consumer products. When using this part, observe derating above 25 C ambient due to the small QFN-EP thermal pad area, place input and motor bypass capacitors close to the package, and avoid switching the H-bridge without proper dead-time management - the internal logic handles this automatically but motor-wiring inductance must be minimized to reduce EMI on the supply rail. This page synthesizes distributor pricing, drop-in alternative listings, and practical design considerations that go beyond the manufacturer datasheet alone, including pin-by-pin functional descriptions and a cross-brand compatibility assessment for end-of-life planning.
MPC17529EV - 0.7A Dual H-Bridge Motor Driver | NXP | 20-VMFP
The NXP MPC17529EV is a 0.7 A dual H-Bridge motor driver with 3.0 V/5.0 V compatible logic I/O, housed in a 20-pin VMFP (Small Outline) surface-mount package. It is a monolithic dual H-Bridge power IC designed to drive bipolar stepper motors and brush DC motors from a 2.0 V to 6.8 V motor supply, with logic interfaces that operate from a separate 2.7 V to 5.6 V rail. What is an H-Bridge motor driver? An H-Bridge motor driver is a power integrated circuit that uses four switching elements arranged in an "H" topology to drive a DC or stepper motor bidirectionally from a single polarity supply. Two H-Bridges integrated on a single die (a "dual H-Bridge") allow one IC to drive either one bipolar stepper motor (using both bridges as the two windings) or two DC motors (forward/reverse each). H-Bridge motor drivers sit within the broader hierarchy of motor control ICs, which in turn belong to power management semiconductors. By integrating power stage, charge pump, shoot-through protection, and logic interface on-chip, dual H-Bridge drivers simplify portable and battery-powered motion designs. Key features of the MPC17529EV include 700 mA continuous output current per H-Bridge, an integrated charge pump for the high-side drivers, built-in shoot-through current protection to prevent simultaneous turn-on of high-side and low-side FETs, undervoltage lockout for safe startup and shutdown, and parallel MCU-compatible I/O. The two bridges can be paralleled for higher current loads in DC motor applications, or used independently for bipolar stepper drive with microstepping controlled externally. Typical applications include camera lens autofocus and iris mechanisms, disk drive head positioners, bipolar stepper motor actuation in portable printers and scanners, robotic toys, and small DC brushed-motor loads in handheld consumer electronics. Independent control of each H-Bridge via the parallel interface allows flexible step/direction sequencing or dual forward/reverse DC control with minimal firmware overhead. When designing with this part, observe the absolute maximum motor supply voltage and ensure that motor stall current stays within the 0.7 A rating with adequate thermal margin. Place the charge-pump capacitor (CP1, CP2) close to the IC, and follow the datasheet guidance on bulk decoupling at VM and VCC to avoid logic-level noise coupling into the gate drive. This page synthesizes distributor pricing, drop-in alternatives, and design considerations that complement the manufacturer datasheet rather than restating it verbatim.
MPC17529EVEL - 0.7A Dual H-Bridge Motor Driver | NXP Semiconductors
The NXP Semiconductors (formerly Freescale) MPC17529EVEL is a monolithic dual H-Bridge motor driver IC delivering up to 0.7 A continuous output current per bridge in a 20-VMFP (20-pin) package. It operates from a 2.0 V to 6.8 V load supply with 3.0 V/5.0 V CMOS-compatible parallel logic inputs, integrating an on-board charge pump, shoot-through current protection, and undervoltage shutdown in a single chip. An H-Bridge motor driver is a power-IC topology that uses four switches (two high-side and two low-side MOSFETs/ transistors) arranged in an 'H' configuration to drive a DC or bipolar stepper motor winding bidirectionally from a single supply rail. The dual-H topology puts two complete bridges on one die, enabling simultaneous control of two brushed DC motors, one bipolar stepper, or a single higher-current motor with paralleled outputs. Within the broader taxonomy, H-bridge drivers belong to motor drivers, which sit under motor/motion control ICs, which are a subfamily of power management ICs (PMIC). Key features of the MPC17529EVEL include 0.7 A continuous DC output per bridge, low RDS(on) DMOS output stages with built-in shoot-through (cross-conduction) protection, an internal charge pump that eliminates the need for an external bootstrap capacitor on the high-side FETs, parallel 3.0 V / 5.0 V CMOS logic inputs, and an undervoltage lockout that disables the outputs when VCC drops below the operating threshold. The control logic uses simple parallel INx/ENx inputs rather than PWM/PWM logic, simplifying firmware for cost-sensitive designs. Typical applications include bipolar stepper motor drivers for camera lens positioners and disk-drive head actuators, brushed DC motor drivers in portable equipment such as toys, robotics, small appliances, and disk drives, and battery-powered mechanisms needing two-axis motion. The wide 2.0 V to 6.8 V supply range makes it directly compatible with single-cell Li-ion (3.0-4.2 V), two-cell alkaline (2.0-3.2 V), and 5 V regulated rails. When designing with this part, place a 0.1 uF ceramic bypass capacitor as close as possible to the VM and VCC pins to suppress charge-pump switching noise. The exposed pad of the VMFP package must be soldered to a sufficient copper pour to keep junction temperature within the -30 C to +85 C operating range at 0.7 A continuous current.

MPC17531AEVEL - Dual 700mA H-Bridge Motor Driver 20-VMFP | NXP
The NXP Semiconductors MPC17531AEVEL is a monolithic dual H-bridge power IC that delivers up to 700 mA per channel (1.4 A total) from a 2.7 V to 3.6 V logic supply and a 2.0 V to 8.6 V motor load supply, housed in a 20-pin VMFP (SSOP-style) package. It is engineered specifically for low-voltage, battery-powered motion control in portable electronics, where PCB area, quiescent current, and predictable start-up behaviour matter more than absolute current capacity. Each bridge contains four power MOSFETs driven by TTL-compatible CMOS logic, and an internal charge pump supplies the gate drive for the high-side N-channel devices. A motor driver (also called an H-bridge driver or full-bridge driver) is a power-management semiconductor that switches current through a winding in either direction, allowing a DC motor, stepper phase, or voice-coil actuator to spin forward, reverse, brake, or coast. H-bridge drivers sit at the bottom of the motor-control hierarchy: microcontroller -> gate-driver logic -> H-bridge power stage -> motor. The MPC17531AEVEL collapses the gate-driver logic and the power stage into a single IC, removing external bootstrap diodes and level shifters that discrete designs require. Key features include parallel MOSFET output stages with very low on-resistance (typically 0.5 ohm per FET, giving about 1 ohm Rds(on) per half-bridge), built-in shoot-through protection with internal dead-time generation, an enable input for PWM current chopping, and a sleep mode that drops quiescent current to a few microampere for battery standby. The part is specified for an operating junction temperature of -20 C to +150 C, suiting sealed handheld enclosures and industrial modules. The MPC17531AEVEL uses a monolithic BiCMOS process that integrates analog charge-pump circuitry, gate-drive logic, and four power MOSFETs on one die. This integration eliminates the parasitic inductance and timing skew of discrete half-bridges, reducing EMI and improving the predictability of PWM edges at switching frequencies up to 200 kHz. Typical applications include digital-camera zoom and focus motors, cell-phone vibrators and ringers, two-phase stepper drives for lens iris mechanisms, and small brushed DC fans. In each case the part replaces a discrete bridge with four MOSFETs, four gate resistors, a charge pump, and dead-time logic. When designing with this IC, add 0.1 uF ceramic bypass capacitors directly across VM and VCC, and keep the motor leads short to contain inductive ringing. Always observe the 8.6 V absolute-maximum load rating - transients from a stalled motor can exceed the rail. This page consolidates distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
MPC17531ATEP - Dual H-Bridge Motor Driver, 8.6V, 700mA | NXP
The NXP Semiconductors MPC17531ATEP is a monolithic dual H-Bridge power IC designed for portable electronic applications that drive bipolar stepper motors or brush DC motors, including camera lens actuators and disk drive head positioners. Housed in a 24-pin QFN-EP (4x4 mm) package with an exposed thermal pad, it integrates two independent full H-bridges capable of sourcing/sinking up to 700 mA per channel from a 2.0 V to 8.6 V load supply, while the logic interface operates from a 2.7 V to 3.6 V rail. An H-bridge motor driver is a power-IC topology that uses four switching transistors arranged in an H around a load to drive a DC motor bidirectionally or to energize the two phases of a stepper motor. Dual H-bridge ICs like the MPC17531ATEP sit in the power-management / motor-driver hierarchy, between discrete MOSFET bridges and higher-level stepper controller ASICs, and are commonly used where PCB area, BOM count, and shoot-through protection must be minimized in low-voltage portable designs. Key features include integrated shoot-through current protection, independent parallel-mode MCU interface control of each H-Bridge, an internal charge pump that supports the high-side FETs across the full 2.0 V to 8.6 V load range, low on-resistance power MOSFET outputs, and a thermal pad for dissipating the 1.4 A peak per-channel current. The exposed pad also keeps junction temperature within safe limits under continuous bipolar stepper operation at two fans. The architecture uses a parallel input interface rather than SPI/I2C, allowing any MCU GPIO to command forward/reverse/brake modes per bridge in real time. Built-in cross-conduction (shoot-through) protection dead-time eliminates the external logic required with discrete bridges, and the internal charge pump guarantees true rail-to-rail high-side drive at low supply voltages. The device is qualified to industrial operating ranges suitable for consumer and industrial camera actuator designs. Typical applications include camera lens autofocus and zoom drives, disk drive head positioners, robotics in small form factors, and any portable instrument driving 3 V / 5 V brushed DC or bipolar stepper loads. The MPC17531ATEP is well-suited to space-constrained designs that require up to 1.4 A peak per channel without external MOSFETs at three fans. When designing with this device, place a 10 uF bulk capacitor close to the VM pin and 0.1 uF decoupling caps adjacent to VCC, keep logic traces away from the switching power nets, and ensure the exposed pad is soldered to at least 25 mm^2 of top-layer copper. For bipolar stepper microstepping, this part is intended for full-step and half-step use; for true microstepping a higher-resolution controller is recommended at four fans.
MPC17533EV - 0.7A Dual H-Bridge Motor Driver 6.8V | NXP
The NXP MPC17533EV is a 0.7 A dual H-Bridge motor driver IC housed in a 16-pin VMFP (SSOP) surface-mount package with gull-wing leads. It operates from a 2.0 V to 6.8 V motor supply with independent logic-level (2.7 V to 5.7 V) interface, and delivers up to 700 mA continuous output current per channel for portable bipolar stepper and brush-DC motor applications including camera focus/zoom and disk-drive head positioners. A H-Bridge motor driver is a topology that uses four switching FETs arranged in an H configuration to drive a DC motor or one phase of a stepper motor in both directions. The MPC17533 integrates TWO complete H-bridges on a single die, enabling bidirectional control of two DC motors OR full-step/half-step commutation of a single bipolar stepper from a parallel MCU bus. H-Bridges belong to the broader family of motor-driver PMICs (Power Management ICs) used in motion-control electronics. Key features include 0.7 A continuous output current, shoot-through current protection (prevents cross-conduction of the high-side and low-side FETs in each half-bridge), undervoltage shutdown, low RDS(on) CMOS outputs, and parallel MCU interface with 3.0 V / 5.0 V logic compatibility. Each bridge is independently enabled through dedicated IN1/IN2 input pins, and the device includes internal flyback diodes for inductive load switching. The architecture combines bipolar control logic with CMOS power outputs to balance logic-level flexibility with low on-resistance conduction losses. Independent H-Bridge control allows simultaneous driving of two brush-DC motors or interleaved commutation of one bipolar stepper, while the monolithic die construction reduces board area versus discrete MOSFET + gate-driver solutions in portable equipment. Typical applications include camera lens focus/zoom actuators, disk-drive head positioners, bipolar stepper motors in portable instruments, and any low-voltage brushed-DC actuator in consumer electronics. Designers choose this part when a small-footprint, low-dwell dual-driver is needed and total motor current stays below 700 mA per channel. Design consideration: stay under load and ensure the motor supply is decoupled with a low-ESR bulk capacitor placed within 10 mm of the VM pins. Exceeding 700 mA per channel will trigger internal current limit and may damage the die without adequate heatsinking.

Pricing reflects current market levels as of 2026-10-15 and is intended for sourcing decisions.
MPC17533EVEL - 0.7A Dual H-Bridge Motor Driver | NXP Semiconductors
The NXP Semiconductors MPC17533EVEL is a monolithic dual H-Bridge power IC that delivers up to 0.7 A per channel from a 2.7 V to 5.7 V logic supply and a 2.0 V to 8.6 V motor load supply, housed in a 16-pin VMFP surface-mount package. It is designed to drive bipolar stepper motors and brushed DC motors from a single low-voltage CMOS-compatible interface, integrating two full H-bridges with parallel MCU control and built-in shoot-through protection. An H-Bridge motor driver is a power-management IC category that uses four switching transistors arranged in an H topology to bidirectionally drive a DC or stepper motor winding. Within the broader taxonomy, MPC17533EVEL belongs to motor drivers > motor motion and ignition controllers > power management ICs > semiconductors. The dual-H architecture allows independent control of two windings, making a single IC able to commutate a bipolar stepper motor or two independent brushed DC motors. Key features include 0.7 A continuous output current per bridge, low on-state resistance FET outputs, parallel MCU interface compatible with 3.0 V and 5.0 V logic, independent H-bridge control inputs, undervoltage shutdown, and built-in shoot-through current protection that prevents both high-side and low-side FETs from conducting simultaneously. Operating quiescent current is held low to preserve battery life in portable applications. The architecture uses CMOS control logic driving DMOS power stages, allowing fast switching edges while keeping the interface powered from the same rail as a typical microcontroller. Internal logic-level translation removes the need for external gate drivers, and the parallel interface lets the MCU set forward/reverse/brake directly per bridge without an SPI/I2C transaction overhead. Typical applications include camera autofocus and zoom actuators, disk drive head positioners, lens iris controls, camera shutter mechanisms, and portable point-of-sale printers. The 2.0 V to 8.6 V motor supply range also covers small pumps and valves in instrumentation. When designing with this part, place ceramic bypass capacitors (10 uF bulk + 0.1 uF high-frequency) as close as possible to the VM and VCC pins. Use separate PCB traces or planes for the motor load and digital logic returns to avoid high-di/dt motor current spikes coupling into the logic reference. This page synthesizes distributor pricing, parametric comparison against same-package alternatives, and practical design notes that complement the NXP datasheet.
MPC17550EVEL - Dual H-Bridge Motor Driver IC | NXP Semiconductors
The NXP Semiconductors MPC17550EVEL is a dual H-bridge DC motor driver integrated circuit capable of driving two bidirectional brushed DC motors or one stepper motor, housed in a 20-pin HVQFN (EVEL) exposed-pad package. It operates from a motor supply range of 2.0V to 5.5V (VCC) with charge-pump support for the high-side drivers, and delivers up to 1.0 A continuous / 3.8 A peak output current per bridge. The part is engineered for low-voltage, battery-powered motion applications including camera lens focus/zoom control, lens shutters, and stepper actuator drive. A brushed DC motor driver (also called an H-bridge) is a discrete or integrated power stage that uses four switches arranged in an H topology to reverse the polarity of voltage applied to a motor winding. Two H-bridges on one die enable independent bidirectional drive of two motors, or sequential phase drive of a bipolar stepper. Compared with discrete MOSFET half-bridges, an integrated dual H-bridge reduces PCB area, eliminates gate-drive timing concerns, and adds built-in protection such as undervoltage lockout, short-circuit shutdown, and thermal shutdown. This places the MPC17550EVEL within the broader hierarchy of motor driver IC -> motion driver -> power management IC -> semiconductor. Key features include 1.0 A continuous RMS output current per H-bridge (3.8 A peak), ultra-low RDS(on) of typically 0.18 ohm per high-side and low-side FET at TA=25C, an integrated charge pump requiring a single 0.1 uF CP capacitor, and independent logic-level IN1/IN2 + EN pins per bridge. The IC includes cycle-by-cycle current limiting, thermal protection, and under-voltage lockout (UVLO) on VCC. The device architecture pairs four N-channel MOSFETs per bridge with a switched-capacitor charge pump to generate a gate voltage above VCC, allowing 100% duty-cycle operation of the high-side FETs without bootstrap refresh. Logic inputs are 1.8V-5V CMOS-compatible, permitting direct connection to microcontrollers without level shifters. Internal dead-time generation prevents cross-conduction between half-bridges. Typical applications include camera module autofocus / zoom (voice-coil motor drive), stepper motor drive in camera shutters and aperture actuators, small brushed DC gearmotor drive in consumer electronics, optical image stabilization actuator control, and low-power robotic actuators. The 20-pin HVQFN with exposed die pad enables direct PCB thermal dissipation in space-constrained modules. When designing with this part, place the 0.1 uF charge-pump capacitor as close to the CP pin as possible and provide a low-impedance GND plane tied to the exposed pad. Verify thermal performance at the user's worst-case duty cycle, since 1 A continuous into 1 ohm load dissipates approximately 1 W per bridge - four-layer PCB with thermal vias under the EP is recommended. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes from the NXP MPC17550 datasheet that go beyond what a manufacturer PDF alone provides.
MPC17559EP - Quad H-Bridge Low-Voltage Motor Driver | NXP
The NXP MPC17559EP is a monolithic quad H-Bridge motor driver IC designed for low-voltage portable electronics, integrating four independent half-bridge output stages capable of delivering up to 300 mA per channel. Housed in a 56-pin QFN (8x8 mm) surface-mount package with an exposed thermal pad, the part is built on a Power MOSFET parallel architecture and operates from a supply voltage of 1.8 V to 3.5 V with a load voltage range of 0.9 V to 3.5 V. Internal charge-pump generation, four MOSFET half-bridges, and logic-level serial/parallel control inputs are combined on the same die, eliminating the need for external gate drivers or bootstrap capacitors in low-voltage applications. A motor driver is a power-management IC that converts low-current logic signals from a microcontroller into the high-current phase voltages required by DC, stepper, or brushless DC (BLDC) motors. In the broader power-electronics taxonomy, the MPC17559EP sits within the motor-driver category, itself a subset of motion-control ICs under power management; it descends from the H-bridge topology that uses four switches to reverse current flow through a DC motor, enabling bidirectional rotation. The MPC17559 extends this topology with two parallel 3-phase outputs plus two H-bridges on a single die, which is unusual at this footprint size and supports extremely compact camera/lens or vibration-module designs. Key features include 300 mA continuous output current per channel, integrated over-current and thermal protection, low quiescent current to preserve battery life, and a low on-resistance Power MOSFET output stage. The 56-QFN package achieves a thermal resistance (theta JA) suitable for natural-convection cooling on a 1 oz copper PCB land, while the exposed pad provides direct heat dissipation into the board. The internal architecture uses four N-channel Power MOSFETs with common-drain outputs arranged as two configurable 3-phase bridges and two H-bridges. Logic inputs accept 1.8 V CMOS levels directly from modern microcontrollers, eliminating the need for level shifters. The chip targets portable applications where board area and standby current dominate design priorities. Typical applications include camera lens autofocus drivers, vibrator and stepper motor control in mobile phones, BLDC cooling fans, two-phase stepper indexing, and dual-coil DC actuator driver stages. Designers favor the part when four motors must be driven concurrently from a single lithium-ion or USB-supplied rail. When designing with the MPC17559EP, evaluate total worst-case dissipation against the package thermal envelope. At VIN=3.5 V driving four channels at 300 mA simultaneously, dissipation is non-trivial and requires generous copper thermal vias under the exposed pad; however, the part's wide logic compatibility usually eliminates external level-shifters and reduces overall BOM cost. This page consolidates distributor pricing, same-package drop-in alternatives, and practical PCB thermal notes not offered by the manufacturer datasheet, helping engineers evaluate MPC17559EP for next-generation portable designs.
MPC17559EPR2 - Quad H-Bridge Motor Driver, 56-QFN | NXP
The NXP MPC17559EPR2 is a monolithic quad H-Bridge motor driver IC with parallel interface and Power MOSFET outputs, housed in a 56-pin QFN (8x8) package. It operates from a 1.8V to 3.5V logic supply, drives loads from 0.9V to 3.5V, and delivers up to 300 mA per output channel. The device supports brushed DC and brushless DC (BLDC) motors in a fully integrated control-and-power-stage architecture. What is a motor driver IC? A motor driver IC bridges a low-power microcontroller or logic controller (typically 1.8V–5V) and a higher-current electromechanical load, providing the level-shifting, current amplification, and protection (current limit, thermal shutdown, flyback handling) required to safely energize windings. Motor drivers sit within the broader Power Management IC family, alongside voltage regulators and DC-DC converters; the H-bridge topology in particular enables bidirectional rotation of brushed motors and bidirectional current control in stepper or BLDC phase windings. Key features include four independent H-bridge channels, half-bridge (10) output configuration, parallel logic control, integrated freewheeling diodes, and thermal shutdown. Each H-bridge can sink/source continuous DC current into resistive, inductive, or DC-motor loads, making the MPC17559EPR2 suited for portable equipment with multiple low-voltage motors. The 56-QFN package (8 mm x 8 mm) provides a low-profile footprint for space-constrained PCB designs. Architecturally, the MPC17559EPR2 integrates Power MOSFET output transistors with logic-level input translation directly on the same silicon die. The parallel command interface (latch-based or direct) allows deterministic, low-latency motor control from a microcontroller GPIO port without an SPI or I2C transaction overhead. Built-in shoot-through protection prevents cross-conduction during state transitions. Typical applications include camera lens autofocus and zoom drives in digital cameras, dual-axis camera positioning stages, dual stepper motor drives in portable printers, vibrator motors in mobile devices, and BLDC fan speed controllers. The combination of four bridges in a single package is uncommon, which is why this part is selected in designs needing to actuate multiple small motors from a compact module. When designing with this part, observe the absolute maximum ratings on the logic and load supply rails. Add bulk decoupling close to both VM and VCC pins, and route high-current motor traces as short and wide as possible to limit parasitic inductance that can stress the internal MOSFETs during PWM switching. This page synthesizes distributor stock and pricing, drop-in alternative analysis, and design guidance not always present on the manufacturer datasheet itself.
