7.1 Overview
The DRV8837C device is an H-bridge driver that can drive one DC motor or other devices like solenoids. The
outputs are controlled using a PWM interface (IN1/IN2).
A low-power sleep mode is included, which can be enabled using the nSLEEP pin.
This device greatly reduces the component count of motor driver systems by integrating the necessary driver
FETs and FET control circuitry into a single device. In addition, the DRV8837C device adds protection features
beyond traditional discrete implementations: undervoltage lockout, overcurrent protection, and thermal shutdown.
