DRV8835DSSR Description


For cameras, consumer items, toys, and other low-voltage or battery-powered motion control applications, the DRV8835DSSR provides an integrated motor driver solution. The device includes two H-bridge drivers that can drive two DC motors or one stepper motor, as well as additional devices such as solenoids. To drive the motor winding, each output driver block consists of N-channel power MOSFETs structured as an H-bridge. Gate drive voltages are generated by an internal charge pump.

The DRV8835DSSR has a maximum output current of 1.5 A per H-bridge. It has a motor power supply voltage of 2 to 11 volts and a device power supply voltage of 2 to 7 volts.

It is possible to pick PHASE/ENABLE and IN/IN interfaces that are compatible with industry-standard devices. Over-current protection, short circuit protection, under-voltage lockout, and overtemperature protection are all built-in.

The DRV8835DSSR is housed in a 12-pin WSON package with PowerPADTM (RoHS compliant and free of Sb/Br).
