DRV8874 Brushed DC Motor Driver Texas Instruments DRV8874 Brushed DC Motor Driver is an integrated motor driver with N-channel H-bridge, charge pump, current sensing, proportional output, current regulation, and protection circuitry. The charge pump improves efficiency by supporting N-channel MOSFET half-bridges and 100% duty cycle driving. The family of devices comes in pin-to-pin RDS(on) variants to support different loads with minimal design changes. An 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. Using the external voltage reference pin, VREF, these devices can regulate the motor current during start-up and high-load events without interaction from a microcontroller. 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, charge pump undervoltage, output overcurrent, and device overtemperature. Fault conditions are indicated on nFAULT.
