3 Description

The DRV8839 provides a versatile power driver

solution for cameras, consumer products, toys, and

other low-voltage or battery-powered applications.

The device has two independent ½-H-bridge drivers

and can drive one DC motor or one winding of a

stepper motor, as well as other devices like

solenoids. The output stages use N-channel power

MOSFETs configured as ½-H-bridges. An internal

charge pump generates needed gate-drive voltages.

The DRV8839 can supply up to 1.8-A of output

current. It operates on a motor power supply voltage

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

of 1.8 V to 7 V.

The DRV8839 has independent input and enable pins

for each ½-H-bridge which allow independent control

of each output.

Internal shutdown functions are provided for

overcurrent protection, short-circuit protection,

undervoltage lockout, and overtemperature.

The DRV8839 is packaged in a 12-pin,

2.00-mm × 3.00-mm WSON package (Eco-friendly:

RoHS and no Sb/Br).
