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).
