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).
