The DRV8231 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 DRV8231 implements a current regulation feature by comparing the analog input VREF and the voltage across a current-sense shunt resistor on the ISEN pin. The ability to limit current can significantly reduce large currents during motor startup and stall conditions.

A low-power sleep mode achieves ultra-low quiescent current draw by shutting down most of the internal circuitry. Internal protection features include supply undervoltage lockout, output overcurrent, and device overtemperature.

The DRV8231 is part of a family of devices which come in pin-to-pin, scalable RDS(on) and supply voltage options to support various loads and supply rails with minimal design changes. See Section 5 for information on the devices in this family. View the full portfolio of brushed motor drivers on ti.com.
