3 Description

The DRV8837C device provides an integrated motor

driver solution for cameras, consumer products, toys,

and other low-voltage or battery-powered motion

control applications. The device can drive one DC

motor or other devices like solenoids. The output

driver block consists of N-channel power MOSFETs

configured as an H-bridge to drive the motor winding.

An internal charge pump generates needed gate

drive voltages.

The DRV8837C device can supply up to 1 A of output

current. The device operates on a motor power

supply voltage from 0 to 11 V, and control logic can

operate on 1.8-V to 5-V rails.

The DRV8837C device has a PWM (IN/IN) input

interface.

Internal shutdown functions are provided for

overcurrent protection, short circuit protection,

undervoltage lockout, and overtemperature.
