3 Description

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).
