3 Description

The DRV883x family of devices 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 Nchannel

power MOSFETs configured as an H-bridge

to drive the motor winding. An internal charge pump

generates needed gate drive voltages.

The DRV883x family of devices can supply up to

1.8 A of output current. It operates on a motor power

supply voltage from 0 to 11 V, and a device power

supply voltage of 1.8 V to 7 V.

The DRV8837 device has a PWM (IN1-IN2) input

interface; the DRV8838 device has a PH-EN

input interface. Both interfaces are compatible with

industry-standard devices.

Internal shutdown functions are provided for

overcurrent protection, short-circuit protection,

undervoltage lockout, and overtemperature.
