The DRV8876QPWPRQ1 is an integrated motor driver featuring an N-channel H-bridge, charge pump, current sense and ratiometric output, current regulation, and protection circuitry. The charge pump improves efficiency by supporting N-channel MOSFET half-bridge and 100% duty cycle drive. This family of devices is available in pin-to-pin RDS(on) variants to support different loads with minimal design changes.

The internal current mirror architecture on the DRV8876QPWPRQ1 IPROPI pin enables current sensing and regulation. This eliminates the need for high power shunt resistors, saving board area and reducing system cost. The IPROPI current sense output allows microcontrollers to detect motor stalls or changes in load conditions. Using an external voltage reference pin, VREF, these devices can regulate motor current during startup and high load events without microcontroller interaction.

The DRV8876QPWPRQ1 low-power sleep mode achieves ultra-low quiescent current consumption 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.
