3 Description

The DRV8835 provides an integrated motor driver

solution for cameras, consumer products, toys, and

other low-voltage or battery-powered motion control

applications. The device has two H-bridge drivers,

and drives two DC motors or one stepper motor, as

well as other devices like solenoids. The output driver

block for each consists of N-channel power

MOSFETs configured as an H-bridge to drive the

motor winding. An internal charge pump generates

gate drive voltages.

The DRV8835 supplies up to 1.5-A of output current

per H-bridge and operates on a motor power supply

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

voltage of 2 V to 7 V.

PHASE/ENABLE and IN/IN interfaces are compatible

with industry-standard devices.

Internal shutdown functions are provided for

overcurrent protection, short circuit protection,

undervoltage lockout, and overtemperature.

The DRV8835 is packaged in a tiny 12-pin WSON

package (Eco-friendly: RoHS and no Sb/Br).
