MPC17517DTBR2 概述
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.

典型应用
MPC17517DTBR2 适用于 6 应用s: Digital/SLR Camera Lens Autofocus, Toy Brushed DC Motor Control, Portable Printer Paper Feed, Solenoid and Valve Driver, Small Robotic Actuator Control, Battery-Powered Lock and Latch.
Digital/SLR Camera Lens Autofocus
The MPC17517DTBR2's 1.2 A peak output current comfortably drives voice-coil lens autofocus, zoom, and iris actuators used in compact digital and SLR cameras. The 3 V to 6.8 V motor supply range matches a single-cell Li-ion battery stack (3.0 V to 4.2 V) commonly used in cameras. The TSSOP-16 footprint has a small PCB area, and the low quiescent current extends standby days. Plugging the driver between the battery and the lens VC motor with 10 uF ceramic bypass on the ML face, the MPC17517DTBR2 dispenses with discrete H-bridge FETs and external flyback diodes - simplifying the camera BOM while still providing thermal shutdown for fault conditions.
推荐
Toy Brushed DC Motor Control
In RC vehicles, robotic toys, and small DC motor drives, the MPC17517DTBR2 supplies 1 A continuous bidirectional drive from 2-cell alkaline packs (3 V to 6.8 V). Its totem-pole output stage handles motor stall currents and integrated flyback diodes absorb inductive kickback when the FETs switch off, eliminating external components. Placed near the motor, the H-bridge protects the host logic from inductive transients and provides thermal shutdown if the motor is stalled, improving product reliability. Compared with a discrete MOSFET H-bridge, the monolithic design is more compact in shops and consumer goods where cost is paramount.
推荐
Portable Printer Paper Feed
The MPC17517DTBR2 powers small brushed DC paper-feed motors in portable thermal printers and label makers. Its 3 V to 6.8 V supply supports a 2-cell Li-ion/USB battery, and the 1.2 A peak drives the paper-feed motor through start-up transients. The TSSOP-16 keeps the circuit compact for motor stalls when the printer is jammed, and the integrated flyback diodes absorb the back-EMF when the motor decelerates. Plugged between the battery and a hub-driver FET array, the MPC17517DTBR2 provides a complete bidirectional drive with one H-bridge chip, replacing four discrete MOSFETs.
推荐
Solenoid and Valve Driver
The MPC17517DTBR2 drives small solenoids, latching valves, and door/relay actuators in portable equipment. Its H-bridge topology applies voltage in either polarity to release magnetic flux for solenoid release and resets the actuator in the opposite direction. Pumping a current spike of 100 A is not feasible - the part is rated for 1.2 A - so it is suited to specific voltage-based solenoids rather than current-based proportional valves. For solenoid pulse applications the built-in thermal shutdown provides a fault signal if the solenoid is shorted, improving product safety.
推荐
Small Robotic Actuator Control
The MPC17517DTBR2 drives small hobbyist and educational robot DC motors from a single Li-ion cell (3 V to 4.2 V) or USB supply (5 V). The TSSOP-16 package is small enough for compact PCB layouts in miniature robots and the integrated flyback diodes absorb motor inductive kickback, removing the need for external components. Plugged between the host microcontroller and the motor with 10 uF MLCC bypass on the ML pins, the MPC17517DTBR2 supplies 1 A of continuous current to the body of a multi-motor robot without external heatsinking.
推荐
Battery-Powered Lock and Latch
The MPC17517DTBR2 is suitable for battery-powered electronic locks, latches, and small electromechanical locks that require bidirectional force from a brushed DC motor or solenoid. Operating from a 3 V to 6.8 V battery stack with 1 A of continuous current, the part drives a small electric door mechanism with positive-deflection reliability. The TSSOP-16 keeps the PCB small enough for compact locks and the H-bridge topology supplies the bidirectional control that single-FET drivers cannot, eliminating the need for separate reverse-polarity circuits.

关键差异点

- Compact TSSOP-16 package （对比 MPC17 series in larger packages)
- Integrated flyback diodes （对比 Discrete MOSFET H-bridge)
设计说明
Decouple both VCC (logic) and VM (motor) supplies separately with at least 0.1 uF ceramic capacitors placed within 3 mm of the respective pins. Add a 10 uF bulk electrolytic or ceramic capacitor on VM sized to absorb the motor's stall-current transient. According to the manufacturer datasheet, VM and VCC must not be tied together when their voltages differ, because back-feeding the logic supply through the body diode of an output FET can damage the part.
Estimated: at VM=5 V, VCC=3.3 V, IOUT=1 A continuous, and an on-resistance of 0.5 ohm per leg, the H-bridge dissipates roughly 1 W of waste heat (P = 2 x I^2 x R_DSON for the two active legs). With a TSSOP-16 theta_JA of approximately 110 C/W, the junction temperature rises about 110 C above ambient. Keep continuous current below 1 A at 25 C ambient, and avoid this configuration for conventional PCB layouts if the application requires 1 A continuous in elevated ambient temperatures.
Route the high-current motor traces (VM, OUT1, OUT2) on a separate PCB layer if possible, and add a thermal copper pour connected to the GND pins to spread heat. According to the manufacturer datasheet, the GND pins should be tied together with low-impedance traces. Use wide motor traces (>= 0.5 mm/20 mil) to minimize voltage drop and I^2R heating.
Do not exceed the absolute maximum VM rating of 6.8 V; transients above 7 V (for example, from a USB hot-plug or inductive kickback) can permanently damage the output FETs. The internal flyback diodes handle motor-deceleration transients, but external TVS protection is recommended if the load includes long motor cables or relays. Reverse polarity on VM will destroy the part - add a Schottky diode or P-FET reverse-polarity protection if the host is battery-powered and user-replaceable.
