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.
