Texas Instruments High-Performance Analog Motor Drivers, Controllers DRV8428PPWPR

The DRV8428PPWPR is a dual H-bridge motor driver designed for various industrial applications, capable of driving one bipolar stepper motor or two bidirectional brushed-DC motors. It operates within a supply voltage range of 4.2 V to 33 V and supports multiple control interfaces, including PHASE/ENABLE and PWM. The device features integrated current sensing with no need for external sense resistors, achieving a full-scale current accuracy of ±6%. It can handle a peak current of 1.7 A and a continuous RMS current of 0.7 A, depending on the PCB design. The DRV8428PPWPR includes several protection features such as undervoltage lockout, overcurrent protection, and thermal shutdown. It also offers a low-power sleep mode with a quiescent current of 2 µA, making it suitable for battery-operated devices. The device is packaged in a compact HTSSOP (16) format, measuring 5 mm x 4.4 mm, which helps save board space. Applications include printers, office automation, robotics, and small home appliances.
