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.\n\nThe 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.\n\nA 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.\n\nThe 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.

The DRV8231A device is an integrated motor driver with N-channel H-bridge, charge pump, current sense feedback, current regulation, and protection circuitry. The charge pump improves efficiency by supporting N-channel MOSFET half bridges and 100% duty cycle driving.\n\nAn internal current mirror architecture on the IPROPI pin implements current sensing and regulation. This eliminates the need for a large power shunt resistor, saving board area and reducing system cost. The IPROPI current-sense output allows a microcontroller to detect motor stall or changes in load conditions. The external voltage reference pin, VREF, determines the threshold of current regulation during start-up and stall events without interaction from a microcontroller.\n\nA 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.\n\nThe DRV8231A 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.
