7 Detailed Description
7.1 Overview
The DRV883x is a H-bridge driver that can drive one DC motor or other devices like solenoids. The outputs are
controlled using either a PWM interface (IN1/IN2) on the DRV8837 or a PH/EN interface on the DRV8838.
A low-power sleep mode is included, which can be enabled using the nSLEEP pin.
These devices greatly reduce the component count of motor driver systems by integrating the necessary driver
FETs and FET control circuitry into a single device. In addition, the DRV883x adds protection features above
traditional discrete implementations: undervoltage lockout, overcurrent protection, and thermal shutdown.
