DRV8832,pdf(Low-Voltage Motor Driver IC)

The DRV8832 provides an integrated motor driver soluTIon for battery-powered toys, printers, and other

low-voltage or battery-powered moTIon control applicaTIons. The device has one H-bridge driver, and can drive

one DC motor or one winding of a stepper motor, as well as other loads like solenoids. The output driver block

consists of N-channel and P-channel power MOSFET’s configured as an H-bridge to drive the motor winding.

Provided with sufficient PCB heatsinking, the DRV8832 can supply up to 800-mA of conTInuous output current. It

operates on power supply voltages from 2.9 V to 6 V.

To maintain constant motor speed over varying battery voltages while maintaining long battery life, a PWM

voltage regulation method is provided. An input pin allows programming of the regulated voltage. A built-in

voltage reference output is also provided.

Internal protection functions are provided for over current protection, short circuit protection, under voltage

lockout and overtemperature protection.

The DRV8832 also provides a current limit function to regulate the motor current during conditions like motor

startup or stall, as well as a fault output pin to signal a host processor of a fault condition.

The DRV8832 is available in 10-pin MSOP and WSON packages with PowerPAD™ (Eco-friendly: RoHS & no

Sb/Br).
