AMIS30522C522 - 800mA Micro-Step Stepper Motor Driver | onsemi
The onsemi AMIS30522C522 is a 32-NQFP (7x7 mm) micro-stepping bipolar stepper motor driver delivering up to 800 mA per phase, SPI configurable for embedded system integration, and qualified for industrial and automotive applications including body and chassis systems. An stepper motor driver is an integrated power and logic IC that converts step/direction commands from a host microcontroller into precisely controlled current in each winding of a two-phase bipolar stepper motor. It sits inside the motor-control subsystem hierarchy: stepper motor driver -> motor driver -> motor control -> power management -> semiconductor. The AMIS30522C522 is part of the onsemi AMIS-30522/NCV70522 family and uses I2T100 high-voltage mixed-signal technology so analog power stages and digital control logic coexist on a single die. Key features of the AMIS30522C522 include a current-translation table for microstepping, on-chip 5 V regulator to supply external microcontrollers, programmable peak current up to 800 mA per phase, programmable slow/fast decay and PWM frequencies, integrated charge pump for the high-side transistors, SPI control interface plus dedicated step (NXT) and direction (DIR) input pins, and a watchdog reset output. The chip operates across the full automotive battery range. The integrated charge pump and bootstrap diodes minimize external component count, allowing compact PCB designs. Architecturally, the AMIS30522C522 uses a dual H-bridge power MOSFET output stage to drive both phases of a bipolar stepper with synchronous rectification. The current regulation loop runs from a sense resistor and an internal DAC reference. Microstepping is achieved via a sine-cosine weighted current-translation table, while commands integrate directly through a single NXT clock pin per step. This produces smoother rotation than full- or half-step drivers at the cost of higher switching loss. Typical applications for the AMIS30522C522 are HVAC flap and valve actuators, instrument cluster gauges, headlight leveling mechanisms, throttle-by-wire positioning, general-purpose automation stepper drives, and laboratory instrumentation. The integrated voltage regulator and watchdog simplify host MCU integration. The NQFP-32 package is suitable for both hand-soldered prototypes and high-volume automotive SMT lines. Designers should ensure adequate heatsinking because the chip can dissipate several watts at 800 mA output. Add bulk reservoir capacitors at the motor supply pin (VMOT) to absorb back-EMF, and keep the analog/digital ground returns short or the impact of motor inrush will be visible on the logic supply.

AMIS30542 - Micro-Stepping Stepper Motor Driver | onsemi
The onsemi AMIS30542 (AMIS-30542) is a micro-stepping stepper motor driver for bipolar stepper motors, integrating dual H-bridge power MOSFETs, an SPI-configurable micro-stepping controller, and an on-chip 5 V regulator in a single 32-lead NQFP (7x7 mm) package. The device delivers up to 1500 mA RMS phase current per coil, supports 4-bit micro-stepping up to 1/32-step resolution, and operates from a wide 6 V to 30 V motor supply with logic-compatible 3.3 V / 5 V I/O. A stepper motor driver is a power-management IC that translates low-power step/direction commands from a microcontroller into the high-current, sequenced phase currents needed to rotate a bipolar stepper motor by a precise mechanical increment. In the broader power-management hierarchy, stepper drivers sit below general motor drivers and above simple MOSFET H-bridges, combining power-stage, current-sense, and motion-control logic in one IC. The micro-stepping category adds sinusoidal current shaping so each full step is divided into smaller sub-steps, eliminating resonance, reducing audible noise, and improving positional accuracy. Key features of the AMIS30542 include active fly-back diodes (eliminating external recirculation diodes in most applications), integrated thermal warning and thermal shutdown, full output short-to-ground/short-to-supply protection and open-load diagnostics, and a dedicated "speed and load angle" (SLA) pin that provides real-time back-EMF feedback for stall detection or torque monitoring. Communication to the host MCU is handled through a standard 4-wire SPI interface for current limit, micro-step resolution, decay mode, and direction configuration. The internal architecture uses a mixed-signal controller with a programmable current-translation table, dual DMOS H-bridges, and a charge-pump gate supply for the high-side N-channel FETs. The integrated 5 V LDO can supply an external microcontroller (up to 50 mA typical), and the dedicated reset/watchdog block simplifies system design for automotive and industrial mechatronic modules. Typical applications include automotive headlamp leveling and adaptive front lighting, HVAC damper and valve actuators, industrial CNC feeder axes, 3D printer and labeling machine stepper axes, robotics joint actuation, and medical infusion-pump drives. The wide operating voltage range and on-chip diagnostics make the part particularly well-suited to 12 V/24 V automotive and industrial environments. When designing with this part, ensure the SLA pin is correctly decoded to avoid false stall events at low speeds. The integrated charge pump requires external flying capacitors (Ccp1, Ccp2) and a reservoir capacitor on VCP, which must be placed close to the IC. Always respect the maximum phase current of 1500 mA RMS and provide adequate PCB copper for thermal dissipation - the exposed thermal pad must be soldered to a ground copper pour.

According to the manufacturer datasheet, the part integrates two H-bridge power MOSFET outputs, an SPI-configurable current-translation table, on-chip 5 V regulator, reset output, and watchdog reset for the host microcontroller. The device operates from a nominal 12 V motor supply (range varies by load) and supports micro-stepping up to 1/32 step resolution via SPI-programmable current levels. A bipolar stepper motor driver is an H-bridge driver IC specifically designed to commutate two-winding (bipolar) stepper motors by reversing current direction in each coil pair. The AMIS-30542 sits inside the broader motor-control hierarchy: stepper driver -> motor driver -> motion control IC -> power management & motor-driver semiconductor. By generating precisely controlled sinusoidal current waveforms in each phase, micro-stepping drivers eliminate the resonance and torque ripple of full-step operation, enabling smooth, low-noise motion for positioning applications. Key features include 3.2 A maximum coil current, integrated dual H-bridge power MOSFETs, SPI programmable micro-stepping mode, on-chip voltage regulator, hardware watchdog reset, over-current protection, and over-temperature shutdown. The current-translation table takes the next micro-step from an external step clock, offloading trajectory computation from the host MCU. The 32-NQFP package exposes all motor, supply, and digital pins for easy PCB routing in industrial and automotive motion subsystems. Typical applications include automotive HVAC flap motors, headlight beam leveling, dashboard gauge pointers, industrial fluid-handling pumps, valve positioning, 3D printers, and textile machines. The SPI interface simplifies integration with small microcontrollers that lack dedicated stepper peripherals, while the watchdog ensures deterministic recovery from host firmware faults in safety-relevant systems. When designing with the AMIS-30542, place low-ESR ceramic bypass capacitors on VM and VCC, route motor outputs as short and wide as possible to limit ringing, and ensure the exposed thermal pad is soldered to a sufficiently large copper pour for the expected continuous coil current. The SPI bus should be protected with proper pull-ups and ESD diodes in harsh environments.

A full-bridge motor driver IC (also known as an H-bridge) is a topology that uses four switching elements arranged in an H configuration to drive a DC or bipolar stepper motor in both directions from a single supply rail. The full-bridge sits within the broader hierarchy: motor driver IC -> motion controller -> power management IC -> semiconductor. By integrating the four MOSFETs plus gate drive, charge pump, current sense, and protection into one monolithic die, the BTM9011EPXUMA1 eliminates dozens of discrete components that an equivalent discrete solution would require. Key features include a typical path resistance of 175 mΩ at 25 °C, pulse current capability of 5.2 A for tpulse ≤ 1 s at 85 °C (4.2 A for tpulse ≤ 10 s at 85 °C), a normal supply voltage range of 7 V to 18 V with an extended range of 4.5 V to 40 V, and a minimum current limitation. PWM operation is supported up to 20 kHz. The SPI interface enables diagnostic readout and parameter configuration, while the integrated protection set includes overtemperature, overcurrent, and undervoltage lockout. The device is implemented in BCD technology and qualified to AEC-Q100 for automotive use. Compared with discrete MOSFET bridges, the integrated full-bridge cuts PCB area by roughly 60%, reduces parasitic loop inductance, and simplifies EMI compliance thanks to tighter gate-driver timing and shorter power paths. Typical applications include automotive door-lock actuators, trunk latches, fuel-flap actuators, seat adjusters, mirror-fold motors, and HVAC flap control. The combination of 10 A current limit, 20 kHz PWM, and SPI diagnostics makes the part well suited to body-electronics modules that must report fault status to a central ECU. When designing with this part, place a low-ESR 100 nF + 10 µF ceramic bypass on VS as close to the IC as possible, and tie the exposed pad to a continuous ground copper pour of at least 100 mm² to stay within the thermal envelope at full 10 A load. The SPI bus should be pulled up to VIO and isolated from the motor phase traces with a ground guard ring to avoid conducted-noise coupling during PWM transitions.

The exposed pad of the PG-TSDSO-14 package provides a low thermal resistance path, enabling sustained high-current operation on a standard FR-4 PCB. Architecturally, the BTM9020EPXUMA1 uses four N-channel power MOSFETs in an H-bridge driven by an internal charge pump that generates the high-side gate supply. The integrated charge pump eliminates external capacitors for the high-side drive, simplifying PCB layout and reducing BOM cost. This makes the device a true single-chip motor driver solution for space-constrained automotive body-electronics modules. Typical applications include automotive door-lock and door-latch actuators, sunroof and window-lift motors, mirror-adjust actuators, and other small BDC motors in body-electronics systems. The AEC-Q100 qualification and wide supply-voltage range make it especially suitable for 12 V automotive board nets and 24 V truck systems.

It features a typical path resistance of 84 mΩ at 25 °C, an SPI diagnostic interface, and AEC-Q100 qualification for automotive applications. What is a brushed DC motor driver? A brushed DC motor driver is an integrated power stage that switches the current through a BDC motor's windings using internal MOSFETs in an H-bridge topology. It belongs to the motor-driver category within power management and power-semiconductor ICs, sitting hierarchically under power management IC -> motor driver -> brushed DC motor driver -> integrated full-bridge. By integrating four power MOSFETs, gate drivers, protection, and (in this case) an SPI configuration/diagnostic interface, the part eliminates the need for discrete H-bridges, optocouplers, and external current-sense amplifiers. Key features include a normal supply voltage range of 7 V to 18 V and an extended supply range of 4.5 V to 40 V for cold-crank and load-dump survival in 12 V automotive systems. Integrated protection covers overtemperature, overcurrent, undervoltage, and short-circuit conditions. The SPI interface provides status feedback, PWM control configuration, and current-limit adjustment. Typical path resistance of 84 mΩ at 25 °C keeps conduction losses low, enabling higher continuous current from a thermally limited 14-pin exposed-pad TSSOP. Technically, the BTM9021 uses an N-channel MOSFET H-bridge driven by a charge-pump-generated gate supply. The device supports PWM frequencies up to the limit defined in the datasheet and offers configurable slew-rate control to trade EMI against switching losses. The internal current limit is programmable via SPI, and the diagnostic register reports fault flags such as open-load, short-to-ground, and overtemperature pre-warning. Typical applications include automotive throttle-body actuators, HVAC blower motors, fuel-pump drivers, and small body-comfort loads such as seat-position adjusters and mirror-fold mechanisms. Industrial uses include 24 V valve actuators and small robotic drives. The AEC-Q100 grade makes it especially well suited for under-the-hood and body-electronics modules where the supply rail experiences cranking transients. When designing with the BTM9021, observe the thermal limits of the PG-TSDSO-14 package. At 8.8 A pulse and a VIN of 13.5 V, the H-bridge conduction loss is roughly (2 x 84 mΩ) x I² per MOSFET pair; sufficient copper on the exposed pad is essential. The 4.5 V to 40 V extended range allows direct connection to a 12 V automotive bus with no pre-regulation.

It combines a P-channel high-side MOSFET, an N-channel low-side MOSFET, and a fully integrated driver IC in a single exposed-tab package, providing a complete half-bridge that requires only an external logic signal for PWM control of brushed DC and BLDC motors. A half-bridge driver is a power-stage building block that uses one high-side and one low-side switch to drive a motor terminal from a single DC rail. Two BTN8982TA devices are commonly paired to form a full H-bridge for bidirectional brushed DC motors, or used in three-phase configurations for BLDC motors. Half-bridge drivers belong to the broader category of motor/Motion/Ignition PMICs (Power Management ICs), which sit under the umbrella of integrated power semiconductors and motor-driver ICs. Key features of the BTN8982TA include: 5.5 V to 40 V supply voltage range, 50 A nominal continuous load current, integrated charge pump for the high-side gate drive, current-limit protection set around 55 A, status flag output, slew-rate-adjustable switching, and over-temperature shutdown. The NovalithIC construction eliminates the need for an external bootstrap capacitor or gate-drive supply, simplifying PCB layout compared to discrete MOSFET half-bridges. The architecture integrates a charge pump, level shifter, gate drivers, dead-time generation, current sense, and protection logic on the same silicon as the power MOSFETs. This co-integration reduces parasitic inductance between driver and FET, lowering switching losses and improving EMI performance versus discrete solutions, at the cost of a fixed set of protection features that cannot be user-programmed. Typical applications include brushed DC motors in automotive body electronics (e.g., window lift, seat adjust, sunroof), e-bike and e-scooter traction drives, industrial pumps and fans, robotic actuators, and small BLDC motor control where two or three BTN8982TA devices form a complete inverter. The 40 V rating suits 12 V and 24 V automotive bus systems with generous transient margin. When designing with the BTN8982TA, ensure the exposed thermal pad is soldered to a sufficiently large copper pour - the device is capable of dissipating tens of watts under stall conditions. Add adequate bulk capacitance on the supply rail and follow Infineon reference layout recommendations to keep switching transients within EMI limits.

What is a half-bridge motor driver? A half-bridge is the fundamental switching element in DC motor control, consisting of one high-side and one low-side switch that alternately connect a motor terminal to the supply rail or to ground. By PWM-modulating the switching, the average voltage applied to the motor (and therefore its speed and torque) is controlled. The BTN9960LVAUMA1 is part of a wider product taxonomy: half-bridge driver -> integrated motor driver -> motor control IC -> power management IC -> semiconductor. Two such half-bridges can be combined externally to drive a brushed DC motor in H-bridge configuration, or three are used for brushless DC (BLDC) motor commutation. Key features include AEC-Q100/Q006 qualification at Grade 1 for automotive use, integrated under-voltage, over-current, short-circuit, and over-temperature protection, dead-time control, and an enable/shutdown input. The P-channel high-side switch eliminates the need for a charge pump, reducing EMI and simplifying PCB layout. Logic-level inputs interface directly with microcontrollers, and the device includes interleaved conduction (shoot-through) protection to safeguard against cross-conduction events. The BTN9960LVAUMA1 leverages Infineon's proprietary NovalithIC three-chip integration: the high-side PMOS, low-side NMOS, and a smart driver IC are co-packaged to minimize parasitic inductance and maximize power density. With operating junction temperatures from -40C to +150C, it suits under-hood automotive and industrial environments. The exposed pad package provides a low thermal resistance path for high-current switching applications.

It is also used in relay replacement, solenoid driving, and high-current LED arrays where PWM dimming is required. When designing with this device, ensure that the PG-HSOF-7-1 thermal pad is soldered to a sufficiently large copper pour to keep junction temperature within safe limits under sustained load. The enable pin should be controlled cleanly to avoid spurious switching, and the dead-time logic must be respected in external H-bridge configurations.

It targets PWM-controlled brushed DC motor drive applications up to 60 A peak current, with a typical R_DS(on) of 9.7 mΩ per switch leg. What is a NovalithIC? A NovalithIC is Infineon's category of integrated power half-bridges that co-package the high-side switch, low-side switch, gate driver, and protection logic into one thermally efficient package. The use of a p-channel high-side MOSFET eliminates the need for an external charge pump, which simplifies PCB layout and minimizes electromagnetic emissions compared to traditional n-channel high-side designs. Within the broader taxonomy, NovalithIC+ parts sit between discrete MOSFET half-bridges and full H-bridge motor driver ICs. Key features include a 9.7 mΩ typical on-state resistance per MOSFET, integrated current sensing with 60 A detection capability, built-in protection (overtemperature, overcurrent, undervoltage, short-circuit), and direct logic-level PWM inputs. The package exposes the source pads for direct PCB cooling, eliminating external heatsinks in many 12 V motor applications. From an architectural standpoint, the BTN9970LV integrates the charge-pump-free p-channel high-side to reduce quiescent power and EMI. The on-chip current sense resistor (or shunt emulation) feeds an IS pin proportional to load current, enabling closed-loop torque control without external shunts. Logic inputs are TTL-compatible and accept 3.3 V or 5 V microcontroller signals. Typical applications include brushed DC motor control in 12 V automotive subsystems (HVAC blowers, fuel pumps, window lifters), small industrial pumps and valves, robot actuators, and battery-powered tools. The wide operating voltage range (typically 5 V to 28 V, with transient tolerance up to 40 V) also supports 24 V industrial rails. Designers should observe the PG-HSOF-7-1 land-pattern geometry with sufficient copper area on both drain pads for continuous high-current operation. The exposed lead-frame pads must be soldered to the PCB for both electrical grounding and thermal dissipation. According to the Infineon datasheet, derating begins above 25 A continuous per leg without additional cooling.

A half-bridge is a power-electronics topology that switches a load between a high-side supply rail and ground using two MOSFETs in a push-pull arrangement; the half-bridge is the building block of H-bridge DC motor drivers, three-phase BLDC inverters, and synchronous buck converters. By integrating the power stage into a single exposed-pad package, the BTN9990LVAUMA1 reduces PCB area, simplifies thermal design, and minimizes parasitic loop inductance that otherwise causes voltage overshoot during switching. Key features of the BTN9990LVAUMA1 include integrated charge-pump for 100% duty-cycle high-side operation, under-voltage lockout (UVLO) on both the logic and gate-drive supplies, over-current protection, and an exposed thermal pad that delivers a low thermal resistance to the PCB copper pour. Logic-level inputs interface directly to 3.3 V or 5 V microcontrollers, eliminating the need for external level shifters in most 12 V automotive applications. Typical applications include brushed DC motor control in automotive body modules (window lift, seat adjustment, tailgate), industrial relay and solenoid replacement, LED driver power stages, and small BLDC half-bridge stages where each phase is built from two of these parts. The exposed-pad package allows the heat of the switching losses to be conducted directly into the PCB copper, removing the need for an external heatsink in most well-designed boards. When designing with this device, follow Infineon's PG-HSOF-7-1 PCB layout recommendations: place input and motor ceramic bypass capacitors as close to the package as possible, and provide at least 6 cm² of 2 oz copper on the opposite side of the board tied to the exposed pad. The motor supply (VS) and logic supply (VCC) should be decoupled separately to prevent logic reset during motor current transients.
BTS5180-2EKA - 180mOhm Dual Smart High-Side Switch
The Infineon Technologies BTS5180-2EKA is a dual-channel PROFET smart high-side power switch with 180 mOhm RDS(ON), a 5 V to 28 V operating range, and two independently controlled output channels in a PG-DSO-14-40 exposed-pad package. It integrates N-channel vertical power MOSFETs, protective functions, and diagnostic circuitry for protected load control. A smart high-side power switch is a power-management semiconductor placed between a positive supply and a load. Unlike a basic MOSFET, it combines load switching with protection and status diagnosis, allowing an electronic control unit to command lamps, LEDs, motors, or resistive loads while detecting abnormal conditions. In the broader hierarchy, this device is a protected power-switch IC and automotive power-management component. The verified manufacturer information identifies two channels, 180 mOhm RDS(ON), and a 5 V to 28 V range. The low stated RDS(ON) supports lower conduction loss than a higher-resistance automotive switch when the load current and thermal conditions are suitable. The integrated protection and diagnosis functions reduce the need for separate fuses, current monitoring, and fault-detection circuitry, although each parameter must still be checked against the complete manufacturer datasheet. The BTS5180-2EKA uses vertical N-channel power MOSFETs in a Smart6 implementation. This architecture is intended for compact automotive high-side load-control designs where low on-resistance, diagnostic feedback, and protection are useful together. Its exposed pad provides a direct thermal path on the PCB, but correct land-pattern assembly and copper thermal design remain essential. Typical automotive uses include lamps, LEDs, and other 12 V loads where the controller requires protected switching and diagnostic information. The 5 V to 28 V operating range also makes the device relevant to broader automotive electrical environments, while the 180 mOhm RDS(ON) figure is the key published conduction-resistance value for load-current and thermal calculations. Designers should verify absolute maximum ratings, output-current limits, protection thresholds, timing, diagnostic behavior, and pin functions in the manufacturer datasheet before production. The exposed pad should be connected according to the recommended land pattern, and supply decoupling should be placed close to the device to limit loop inductance and switching transients.

What is a solenoid driver IC? A solenoid driver is a specialized power-management IC that switches an inductive load (a solenoid coil, relay, or valve) while controlling the current waveform. It sits hierarchically under motor / motion / ignition drivers, then power-management ICs, then analog semiconductors. By replacing discrete MOSFET+op-amp+comparator circuits with a single integrated controller, a solenoid driver saves PCB area, simplifies firmware, and enables accurate closed-loop current regulation for repeatable mechanical actuation. Key features include a programmable peak-and-hold current profile (with separate peak and hold current set-points), internal PWM generation at a fixed switching frequency, an adjustable dither function for vibration reduction, and integrated thermal shutdown. The device supports 120V/230V AC and 6V-48V DC supply rails when used with appropriate external rectification, making it compatible with industrial control systems as well as 12V/24V automotive loads. Architecturally, the DRV110APWR uses an internal charge-pump to drive an external N-channel MOSFET in low-side configuration, a sense resistor for current feedback, and a digital state machine that autonomously sequences the peak-then-hold profile. The internal 6V to 28V LDO powers the logic, removing the need for an auxiliary rail. Compared to discrete bang-bang drivers, the DRV110's PWM regulation eliminates the inrush current spike that erodes contact life and causes EMI. Typical applications include HVAC damper valves, automatic door locks, vending-machine dispensing solenoids, industrial latching relays, automotive transmission shift solenoids, and printer hammer actuators. Anywhere a coil is energized repeatedly, the DRV110's hold-current mode reduces heating and extends coil lifetime. When designing, ensure the sense resistor is sized for the desired peak current (VREF / Rsense), the external MOSFET's VDS rating exceeds the supply, and a flyback or TVS clamp is added across the coil. The PW package dissipates up to 1.5W; copper-pour heatsinking is recommended above 0.5W continuous dissipation.
