DRV8251 Datasheet 4.1-A Brushed DC Motor Driver

Manufacturer: Texas Instruments

Datasheet Details

The DRV8251 device is an integrated motor driver with N-channel H-bridge, charge pump, current regulation, and protection circuitry.

The charge pump improves efficiency by supporting N-channel MOSFET half bridges and 100% duty cycle driving.

The DRV8251 implements a current regulation
