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.
MPC17C724EP - 0.4A Dual H-Bridge Motor Driver | NXP
The NXP MPC17C724EP is a compact monolithic dual-channel H-Bridge power IC designed to drive bipolar stepper motors or brush DC motors in low-voltage portable applications, delivering continuous motor drive current of 0.4 A per channel with a low on-resistance of 1.0 ohm, supplied across 2.7 V to 5.5 V. It is housed in a 16-pin QFN 3x3 mm package and exposed-pad variant. Built-in shoot-through current protection and an undervoltage lockout at approximately 2.0 V VDD safeguard the H-bridge outputs against fault conditions, and parallel CMOS logic inputs accept 3.0 V or 5.0 V MCU signals directly. A dual H-bridge motor driver is a power-management IC that integrates four switching MOSFETs arranged as two full bridges, allowing bidirectional current control of two DC brush motors or one bipolar stepper motor from a low-voltage digital supply. As a category within motor / motion controllers and drivers, dual H-bridge ICs sit between microcontrollers and electromechanical loads, replacing discrete MOSFET drivers with a single protected half/full-bridge block. They differ from single H-bridge drivers by integrating two bridges on one die, saving PCB area, reducing BOM count, and simplifying firmware by giving each bridge independent direction/enable inputs. Key features of the MPC17C724 include 0.4 A continuous output current per bridge, 1.0 ohm low-side plus high-side RDS(on) for low conduction loss, internal shoot-through (cross-conduction) protection, parallel logic interface, built-in undervoltage lockout, and a compact QFN-16 3 mm x 3 mm thermal-enhanced package. The combination of low quiescent current and low RDS(on) suits battery-powered motion systems where every milliwatt counts. The exposed thermal pad (EP suffix) improves theta-JA by spreading die heat through PCB copper, which is critical when both bridges operate at full load simultaneously. Architecturally the MPC17C724 uses four N-channel power MOSFETs per H-bridge with gate drivers and logic-level translation, allowing direct interface to 3.3 V MCUs. Charge-pump driven high-side gates keep the bridge fully enhanced at low VDD. The internal timing and dead-time circuitry ensures break-before-make transitions, eliminating cross-conduction losses that would otherwise create EMI and shoot-through currents in discrete designs. Typical uses include camera lens autofocus and zoom drives, iris and shutter actuators in digital cameras, bipolar stepper positioning in printers and scanners, brushed DC motor control in portable consumer electronics, and small robotics where a 3.3 V logic MCU drives two low-power brush motors. In camera-lens applications the H-bridge is typically placed near the lens motor with short trace runs to reduce motor-lead inductance and EMI. Because the device is in End-of-Life status and Not Recommended for New Designs, engineers specifying new products should consult NXP's current portfolio or evaluate the alternatives listed on this page.
NJU39610D2 - Dual 7-bit DAC Stepper Motor Controller | DIP-22 | NJR
The Nisshinbo Micro Devices NJU39610D2 is a microstepping motor controller with dual 7-bit+sign digital-to-analog converters (DACs), housed in a 22-pin DIP (D2) through-hole package designed to pair with the NJM3771 precision stepper motor driver. The part provides two independent reference-rail DACs that deliver sinusoidal full-step/microstep current profiles to the dual H-bridge driver, enabling smooth low-vibration motion in two-phase bipolar stepper systems. A microstepping controller is a specialized mixed-signal IC that converts digital position commands (typically from an 8-bit microcontroller such as the 6800/8051/Z80 family) into dual analog reference voltages that command the current setpoint of each motor phase. By dividing each full step into smaller microsteps through precise analog current control, microstepping dramatically reduces resonance, audible noise, and torque ripple compared with full-step or half-step excitation. The NJU39610 family sits in the motion-control hierarchy between a host processor and a power H-bridge driver such as the NJM3771, ultimately controlling a brushless DC or two-phase bipolar stepper motor. Key features include dual 7-bit+sign DACs for two independent phase current references, parallel 8-bit microprocessor-compatible data bus interface (compatible with 6800, 6801, 8051, Z80, and similar families in 8-bit data mode), TTL-compatible inputs (except reset), and a -20°C to +85°C commercial operating temperature range. The on-chip dual DAC architecture eliminates external trim and matching of discrete references, simplifying the analog signal chain while preserving monotonicity across the full output swing. Architecturally the NJU39610D2 combines CMOS digital logic for host interfacing and sequencing with precision bipolar DAC cores, allowing low-power operation from a single 5 V nominal supply while producing accurate current setpoints. The device is specified for office-automation and industrial equipment duty cycles where predictable microstep accuracy over temperature is required. Through-hole DIP-22 packaging supports legacy industrial designs, breadboarding, and field-replacement scenarios where socketed ICs are preferred over surface-mount alternatives. Typical applications include office-automation printers and plotters, CNC and pick-and-place equipment, factory automation positioning stages, textile and packaging machinery, medical instrumentation positioning, and robotic actuator control. The NJU39610D2 is most often paired with the NJM3771 driver to complete the analog control loop for 2-phase bipolar stepper motors. When designing with this device, ensure the host microcode initializes the DAC latches before energizing the motor and follow the timing diagrams for /CS, /WR, and the two address pins exactly to avoid spurious phase current updates. Decouple VCC with a 0.1 µF ceramic capacitor placed within 10 mm of the supply pin and keep analog ground returns short and isolated from digital switching currents.

POWERSTEP01 - 10A SPI Stepper Motor Driver | STMicroelectronics
STMicroelectronics POWERSTEP01 is a bipolar stepper-motor driver system-in-package with eight integrated N-channel power MOSFETs, an SPI-programmable motion controller, and support for motor supplies up to 85 V. It is designed to combine digital motion control and power-stage integration in an 89-VFQFPN package measuring 11 mm by 14 mm. The verified product data identifies a 10 A power-MOSFET class device with 16 mΩ MOSFETs and SPI programmable control. A stepper-motor driver is a motion-control integrated circuit that converts digital position and speed commands into controlled current through the phases of a stepper motor. POWERSTEP01 belongs to the motor-driver and power-management hierarchy: it combines a programmable controller, gate-drive functions, eight N-channel MOSFETs, and protection circuitry. This integration reduces the number of external power components while retaining digital control over speed profiles and positioning calculations. The key feature set centers on the integrated eight-MOSFET power stage, each specified at 16 mΩ in the manufacturer description. The SPI interface allows a host controller to configure motion behavior and retrieve or manage operating functions digitally. The device is intended for demanding motor-control applications where integration, high-voltage operation, and programmable positioning are valuable. Because the package also contains power semiconductors, thermal design, current derating, PCB copper, and motor-supply filtering remain essential. The manufacturer describes POWERSTEP01 as a system-in-package integrating a microstepping controller and 10 A power MOSFETs. Its programmable motion architecture supports speed-profile generation and positioning calculations rather than relying solely on a fixed external step-generation sequence. This makes it suitable for systems where the host processor needs flexible motion configuration, repeatability, and compact implementation. Typical applications include automated machinery, laboratory equipment, CNC and positioning stages, robotics, printers, and industrial motion modules. In each case, the device can sit between a digital controller and a bipolar stepper motor while the motor supply supplies the higher-voltage power domain. The low-voltage logic interface remains distinct from the motor bus, allowing careful isolation, grounding, and signal-integrity design. For implementation, follow the manufacturer datasheet for the exact pinout, electrical limits, thermal conditions, protection thresholds, and recommended PCB layout. Do not assume that a 10 A classification permits 10 A continuously in every motor or ambient condition. The verified information does not provide detailed timing, current-limit, protection-threshold, or package-performance values, so those parameters remain [DATA_NEEDED] and must be confirmed from the datasheet. This page consolidates the verified manufacturer and distributor references, separates confirmed POWERSTEP01 specifications from missing parameters, and provides practical selection and integration guidance for engineers evaluating the device in high-voltage stepper-motion systems.
POWERSTEP01TR - 10A 85V Stepper Motor Driver SPI | STMicro
The STMicroelectronics POWERSTEP01TR is a system-in-package bipolar stepper motor driver integrating a microstepping controller and 8 N-channel 16 mOhm power MOSFETs rated up to 85 V and 10 A, housed in an 89-pin VFQFPN (11x14 mm) exposed-pad package. A stepper motor driver is a power management device that converts digital step and direction commands into precisely sequenced phase currents in a bipolar stepper motor. Within the motion control hierarchy, it sits between the host MCU and the motor windings, replacing discrete gate drivers, MOSFET bridges, and current-sense circuitry with a single SPI-configurable IC. Key features include full digital motion control through speed profile generation and positioning calculations performed on-chip, SPI programmability of all operating parameters, an operating supply range of 7.5 V to 85 V, and up to 10 A output current capability. The integrated 16 mOhm MOSFETs minimize conduction losses, while advanced current control and protection features (overcurrent, thermal) improve system reliability. Technically, the powerSTEP01 executes microstepping current control autonomously, offloading the host processor from real-time phase sequencing. The SPI interface allows configuration of step mode, phase current, acceleration and deceleration profiles, and stall/limit thresholds, simplifying firmware compared to external-step-input drivers. Typical applications include CNC machines, 3D printers, industrial automation, robotics, and textile or packaging machinery, wherever high-current bipolar stepper motors require quiet, accurate microstepping under MCU supervision. Design consideration: the 89-VFQFPN package dissipates significant power at 10 A; the exposed pad must be soldered to a large copper pour or heatsink, and thermal performance must be validated at maximum load. This page adds value beyond the datasheet by synthesizing distributor pricing, package data, and application guidance in one reference.
PS21563-SP - 600V/10A Mini-DIP IPM, 3-Phase IGBT Inverter | Powerex
The Powerex PS21563-SP is a 600V/10A Mini-DIP Intelligent Power Module (IPM) integrating a 5th-generation low-loss three-phase IGBT inverter bridge, high-voltage gate drivers, and comprehensive protection circuitry in a compact dual-in-line transfer-molded package. The module delivers up to 10A continuous collector current at 600V and provides open-emitter outputs designed for small three-phase motor drive applications. With 2500Vrms isolation voltage and built-in HVIC drivers, the PS21563-SP eliminates the need for external gate drive optocouplers and significantly reduces inverter design time. What is an Intelligent Power Module? An IPM (Intelligent Power Module) is a highly integrated hybrid power device that combines IGBT switches, anti-parallel diodes, gate drive HVICs, and fault protection logic in a single transfer-molded package. IPMs sit within the broader hierarchy: power semiconductor -> power module -> IPM -> inverter power stage. They are widely used to shrink PCB area, reduce EMI, and improve reliability compared to discrete IGBT + driver solutions, because the gate drive timing and protection thresholds are pre-engineered by the silicon vendor. Key features of the PS21563-SP include 600V collector-emitter voltage rating, 10A continuous output current per phase, 20A peak output current capability, and built-in protections for short-circuit (SC), under-voltage lockout (UVLO) on each control supply, and over-temperature shutdown. The control logic is 3.3V/5V CMOS-compatible, allowing direct interface with microcontrollers and DSP motor-control peripherals. The 25-pin Mini-DIP transfer-mold package provides 2500Vrms isolation and is optimized for PCB-mount inverter designs where heatsinking is via the mounting base. Architecturally, the PS21563-SP uses 5th-generation IGBT technology with a CSTBT (Carrier-Stored Trench-Gate Bipolar Transistor) structure, achieving lower VCE(sat) and switching losses than prior generations. Each phase leg includes an integrated bootstrap diode and floating supply architecture, allowing a single +15V control rail to drive all three high-side IGBTs through the internal charge pumps. The open-emitter configuration supports both sensored (FOC) and sensorless BLDC/PMSM control algorithms. Typical applications include small three-phase motor drives such as washing machine drum motors, refrigerator compressors, fan and pump inverters, small HVAC blowers, and industrial servo drives up to 750W. The wide control supply range (13.5V to 16.5V) makes it tolerant of regulated 15V rails in industrial 24V bus systems. Design considerations include keeping the P-N1 snubber loop short (≤0.1-0.22μF snubber recommended), placing a 24V/1W Zener diode on each control supply terminal for surge protection, and providing sufficient copper pour on the module base for thermal dissipation (typical Rth(j-c) requires heatsink at sustained loads above 5A).

SI9986CY-T1-E3 - 1A Buffered H-Bridge Motor Driver | Vishay | 8-SOIC
The Vishay Siliconix SI9986CY-T1-E3 is an integrated, buffered H-bridge motor driver Power MOSFET delivering up to 1.0 A continuous output current at VDD = 12 V in an 8-pin SOIC package. The device operates from a 3.8 V to 13.2 V supply range and supports switching rates up to 200 kHz, making it suitable for small DC motor control in camera autofocus, lens iris, and small actuator applications. A buffered H-bridge is a fully integrated motor driver topology that combines four power MOSFETs in an H configuration with on-chip logic-level buffering and shoot-through protection. The H-bridge family belongs to the broader category of motor drivers and motion controllers, which themselves fall under power management integrated circuits. By integrating the power stage and control logic into one die, the buffered H-bridge eliminates the discrete component count and timing headaches of building an H-bridge from individual MOSFETs and gate drivers. Key features include TTL-compatible inputs, internal upper/lower shoot-through protection that prevents simultaneous conduction in either half-bridge, and a bipolar power MOSFET output stage. The integrated design requires no external dead-time circuitry, simplifying PCB layout and reducing BOM cost compared to discrete H-bridge implementations. The device also includes thermal protection and operates over a 0C to 150C junction temperature range. The Si9986 uses an N-channel MOSFET output stage with TTL-compatible logic inputs, allowing direct connection to a microcontroller GPIO without level shifters. The internal charge pump generates the gate drive voltage for the high-side N-channel FETs, while the shoot-through protection ensures that the upper and lower FETs of the same half-bridge cannot turn on simultaneously - a critical feature that prevents destructive cross-conduction currents. Typical applications include camera lens autofocus mechanisms, iris diaphragm control, small DC brushed motor drives in consumer electronics, and any low-power bidirectional DC motor control where PCB area is at a premium. The 8-SOIC package and minimal external component count make it ideal for space-constrained designs. When designing with this device, observe the 13.2 V absolute maximum supply voltage and ensure adequate decoupling with a 0.1 uF ceramic capacitor directly at the VDD pin. The output current rating of 1 A continuous assumes room temperature operation; derate outputs will rise above ambient with reduced PCB copper area.

STSPIN220 - 1/256 Microstep Stepper Driver QFN-16 | STMicroelectronics
The STMicroelectronics STSPIN220 is a low-voltage bipolar stepper motor driver integrating a microstepping sequencer with up to 1/256-step resolution, two PWM current controllers, and a power stage composed of two fully protected full-bridges, housed in a compact 16-pin VFQFPN (3x3x1.0 mm) package. A stepper motor driver is a power management IC that translates low-power control signals into the sequenced phase currents required by bipolar stepper motors. Within the semiconductor hierarchy it sits under motor drivers and motor control ICs, bridging the gap between a microcontroller and the motor coil load. Stepper drivers combine logic (sequencer, translator), current regulation (PWM choppers), and a power stage (H-bridges) in a single device, replacing discrete transistor bridges and simplifying motion-control design. Key features of the STSPIN220 include microstepping resolution as fine as 1/256 of a step for smooth, low-audible-noise motion, an integrated PWM current controller with fixed off-time for accurate coil current regulation, and a low RDS(on) power MOSFET output stage that minimizes conduction losses and heat generation. The device also integrates a full set of protection features, and supports a simple Step/Direction control interface compatible with common 3D-printer and motion-control host architectures. From a technical standpoint, the two fully protected full-bridges drive both phases of a bipolar stepper, while the internal sequencer generates the microstep current profile selected through the microstep mode pins. The PWM current controllers compare the voltage across an external sense element with the reference set by VREF, regulating phase current with fixed off-time chopping. Fully protected operation covers overcurrent and thermal fault conditions, improving system robustness in cost-sensitive designs. Typical applications include 3D printers and 3D-printer stepper driver boards, small robotics and camera-gimbal positioning, laboratory automation, portable battery-powered devices, and low-voltage bipolar stepper actuation up to the 10 V motor-supply class. Its 3x3 mm VFQFPN footprint makes it attractive for space-constrained carrier boards. For design, size the sense resistor so full-scale coil current matches the VREF setting, and provide adequate copper area on the exposed pad for thermal dissipation at higher currents.

STSPIN32F0601TR - 600V 3-Phase BLDC SiP | STM32 | STMicroelectronics
The STMicroelectronics STSPIN32F0601TR is an advanced 600 V three-phase BLDC (brushless DC) motor controller system-in-package (SiP) integrating an ARM Cortex-M0 STM32 microcontroller with 32 KB Flash, a smart gate driver capable of driving N-channel power MOSFETs or IGBTs up to 600 V, and a wide-input linear regulator on a single 64-pin TQFP exposed-pad substrate. Operating from 9 V to 20 V on the supply rail with an embedded 12 V LDO for the gate driver, the device targets home appliances and industrial drives where PCB area, BOM count and reliability dominate the design trade-off. Key headline specs include a 48 MHz Cortex-M0 CPU, 32 KB embedded Flash, 600 V high-voltage rail tolerance on the gate-driver outputs, integrated bootstrap diodes for the three high-side drivers, less than 1 V gate low-level output at 10 mA sink (eliminating external bleeder resistors), an active-low shutdown EN pin, and a smart shutdown comparator that protects the power stage from over-current events. The TQFP-64 10x10 mm package with exposed thermal pad keeps dissipated heat inside the inverter footprint. An LDO (Low-Dropout) linear regulator inside this SiP steps the purpose of a voltage regulator that maintains a stable output even when the input-to-output differential is small; here the 12 V LDO derives the gate-driver VCC from the motor bus, while the MCU core is fed from a separate low-voltage regulator on the same die. The system-in-package concept itself sits within the broader motor-control hierarchy: motor driver IC -> gate driver -> motor controller -> power management IC -> semiconductor. This layered integration is the primary engineering reason designers choose STSPIN32F0601 over a discrete MCU + gate-driver solution. Typical applications include 600 V-class three-phase BLDC/PMSM drives for washing machines, refrigerators, air-conditioner compressors, fans, pumps, industrial servo pumps, and e-bike industrial controllers. The integration also benefits HVAC blower systems and small industrial drives where every millimetre of PCB real estate is at a premium. When laying out the PCB, place the bootstrap capacitors as close as possible to the high-side pins and use a 4-layer board with a continuous ground plane under the exposed pad for thermal relief. Verify that the shunt-resistor value is sized so that the smart-shutdown comparator threshold (200 mV typical on the SD pin) trips before the external MOSFETs exceed their SOA. The SiP is not a hot-swap part; allow at least 1 ms for VCC ramp-up before asserting EN high. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical SiP layout notes that are not found in the manufacturer datasheet, supporting engineers in selecting and qualifying the STSPIN32F0601TR for next-generation high-voltage motor drives.

The high-voltage rail tolerates up to 600 V and the device pairs with external power switches to build complete three-phase inverters for industrial drives, white goods, and home appliances. A system-in-package for motor control combines an MCU core, gate drivers, and housekeeping supplies in a single molded body, dramatically shrinking PCB footprint and bill-of-material versus a discrete implementation. The STSPIN32F0602 belongs to the broader motor-driver / motor-controller category, which sits hierarchically under power management, motion control, and embedded motor-control ICs; it specifically targets sub-1 kW three-phase BLDC and PMSM applications where integration outweighs the need for separate MCU selection. Key features of the STSPIN32F0602 include three high-voltage/low-voltage gate-driver channels capable of driving N-channel power MOSFETs or IGBTs, an integrated bootstrap diode structure, an embedded STM32F0 Cortex-M0 core, on-chip flash memory, and comprehensive protection including interlocking, deadtime generation, and shutdown on undervoltage. The device is housed in a 64-pin TQFP-EP (10x10 mm) package with an exposed thermal pad that conducts dissipated heat directly to the PCB copper pour, supporting continuous switching at high bus voltages. Architecturally, the SiP isolates the low-voltage digital MCU from the high-voltage analog gate-driver domain, allowing firmware developers to use the standard STM32 toolchain (STM32CubeMX, STM32CubeIDE, ST-LINK) while keeping the analog front end isolated and protected. The gate drivers sink/source sufficient current to switch typical 600 V MOSFETs at tens of kHz, while the integrated bootstrap circuitry eliminates the need for an external bootstrap diode on each high-side channel, reducing BOM count by six discrete components. Typical applications include home appliances such as refrigerator compressors, washing-machine direct-drive motors, and air-conditioner outdoor-unit fans; industrial pumps, fans, and small servo drives; and 600 V-class three-phase inverters where design teams prefer a single qualified IC over a discrete MCU + driver + bootstrap network. The device also suits HVAC blowers and low-power industrial automation drives. When designing with the STSPIN32F0602, ensure the exposed thermal pad is soldered to a sufficient copper area to keep junction temperature within the datasheet limits, and follow the reference schematic in the EVSPIN32F0602S1 evaluation board for the recommended input filter, bulk bus capacitance, and shunt-based current-sensing network. Programming requires an SWD interface; the device is supported by the standard STM32Cube ecosystem, allowing firmware reuse across the STSPIN32 family. This page synthesizes distributor pricing, parametric drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone. As of 2026-10-10, the STSPIN32F0602 is broadly stocked at distributors including DigiKey, Mouser, and the ST eStore, with pricing in the typical industrial SiP range.
TB6600 - 5A Stepper Motor Driver IC | Toshiba | CNC
The Toshiba TB6600 (TB6600HG) is a 1-channel bipolar stepping motor driver IC rated for 50V motor supply and 5A (4.0A peak in typical module implementations) output current, delivering microstepping resolution up to 1/16 step in a 25-pin HZIP (HZIP25) power package with integrated MOSFET output bridges. A stepping motor driver IC is a power management device that converts low-current logic-level STEP and DIR pulse signals from a microcontroller into high-current phase currents required by a stepper motor. Within the power electronics hierarchy, it sits between the motor controller (MCU or CNC breakout board) and the motor windings, performing current regulation, microstepping interpolation, and protection functions in a single package. Key features include a wide 9V to 40V DC motor supply range on typical module implementations, output current selectable in 8 steps from 0.7A to 4.0A via DIP switches, and a maximum input pulse frequency of 20 kHz. The device integrates under-voltage lockout (UVLO), over-current detection (ISD), and thermal shutdown (TSD) protection circuits, per the Toshiba product page. The TB6600 uses bipolar power MOSFET output stages in an H-bridge arrangement for each phase, enabling full bipolar drive of 2-phase and 4-phase hybrid stepper motors. Microstepping up to 1/16 reduces torque ripple and audible noise compared with full-step drive. The decoded current decay control maintains smooth phase-current waveforms across the speed range. Typical applications include DIY and light-duty CNC routers, 3D printers driving NEMA 17 and NEMA 23 motors, engraving machines, and small robotics, where optocoupler-isolated signal inputs (on common TB6600 modules) protect the controller from motor-side voltage transients. Design consideration: thermal management dominates the design - at 4A the HZIP package requires a substantial aluminum heatsink, and the manufacturer notes the part is not intended for professional-grade applications. This page synthesizes distributor data, verified specifications, comparisons against DM542, A4988, and TMC2209, and practical design notes not found in the manufacturer datasheet.
