7.1 Overview

The DRV887x family of devices are brushed DC motor drivers that operate from 4.5 to 37-V supporting a wide range of output load currents for various types of motors and loads. The devices integrate an H-bridge output power stage that can be operated in different control modes set by the PMODE pin setting. This allows for driving a single bidirectional brushed DC motor, two unidirectional brushed DC motors, or other output load configurations. The devices integrate a charge pump regulator to support more efficient high-side N-channel MOSFETs and 100% duty cycle operation. The devices operate from a single power supply input (VM) which can be directly connected to a battery or DC voltage supply. The nSLEEP pin provides an ultra-low power mode to minimize current draw during system inactivity.

A variety of integrated protection features protect the device in the case of a system fault. These include undervoltage lockout (UVLO), charge pump undervoltage (CPUV), overcurrent protection (OCP), and overtemperature shutdown (TSD). Fault conditions are indicated on the nFAULT pin.
