DESCRIPTION

The DRV8832-Q1 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-Q1 can supply up to 1-A of DC/RMS or peak output

current. It operates on power supply voltages from 2.75 V to 6.8 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-Q1 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-Q1 is available in tiny 3-mm x 3-mm 10-pin MSOP package with PowerPAD™ (Eco-friendly:

RoHS & no Sb/Br).
