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 MOSFET’s 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 over current protection, short circuit protection, under voltage
lockout and overtemperature.
The DRV8839 is packaged in a 12-pin, 2-mm x 3-mm WSON package with PowerPAD™ (Eco-friendly: RoHS &
no Sb/Br).
