The DRV8836 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 can drive 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 MOSFET configured as an H-bridge to drive the motor winding. An internal charge pump generates gate drive voltages.
The DRV8836 supplies up to 1.5-A of output current per H-bridge. It operates on a power supply voltage from 2 V to 7 V.
PHASE/ENABLE and IN/IN interfaces can be selected which are compatible with industry-standard devices. A low-power sleep mode is provided which turns off all unnecessary logic to provide a very low current state.
Internal shutdown functions are provided for overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature.
The DRV8836 is packaged in a tiny 12-pin WSON package (Eco-friendly: RoHS and no Sb/Br).
