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...
