Texas Instruments  DRV8832QDGQRQ1

The DRV8832-Q1 device provides an integrated motor driver solution for battery-poweredtoys, printers, and other low-voltage or battery-powered motion control applications. The devicehas one H-bridge driver, and can drive one DC motor or one winding of a stepper motor, as well asother loads like solenoids. The output driver block consists of N-channel and P-channel powerMOSFETs 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/RMSor 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 longbattery life, a PWM voltage regulation method is provided. An input pin allows programming of theregulated voltage. A built-in voltage reference output is also provided.

Internal protection functions are provided for over current protection, short-circuitprotection, undervoltage lockout, and overtemperature protection.

The DRV8832-Q1 also provides a current limit function to regulate the motor currentduring conditions like motor startup or stall, as well as a fault output pin to signal a hostprocessor of a fault condition.

The DRV8832-Q1 is available in tiny 3-mm x 3-mm 10-pin MSOP package withPowerPAD™ (Eco-friendly: RoHS & noSb/Br).
