Description for the DRV8832
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 MOSFETs configured as an H-bridge to drive the motor winding.
Provided with sufficient PCB heatsinking, the DRV8832 can supply up to 1 A of DC/RMS or peak output current. The device 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 overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature protection.
The DRV8832 also provides a current limit function to regulate the motor current during conditions like motor start-up or stall, as well as a fault output pin to signal a host processor of a fault condition.
The DRV8832 is available in a tiny 3-mm × 3-mm 10-pin VSON package and MSOP PowerPAD package (Eco-friendly: RoHS & no Sb/Br).
