3 Description
The DRV8832-Q1 device 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 MOSFETs 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,
undervoltage 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).
