DRV8876NPWPR

The DRV8876N is an integrated motor driver featuring an N-channel H-bridge, charge pump, and protection circuitry. The charge pump improves efficiency by enabling N-channel MOSFET half-bridge operation and 100% duty cycle drive. The device family offers pin-to-pin RDS(on) variants to support different loads with minimal design changes. A low-power sleep mode achieves ultra-low quiescent current consumption by shutting down most internal circuitry. Internal protection features include supply UVLO, charge pump undervoltage, output overcurrent, and device overtemperature. Fault conditions are indicated on nFAULT. The DRV887x family are brushed DC motor drivers operating from 4.5V to 37V, supporting a wide range of output load currents for various motor and load types. These devices integrate an H-bridge output power stage capable of operating in multiple control modes configured via the PMODE pin. This enables driving a single bidirectional brushed DC motor, two unidirectional brushed DC motors, or other output load configurations. An integrated charge pump regulator supports more efficient high-side N-channel MOSFET operation and 100% duty cycle operation. The devices are powered by a single supply input (VM) that can be connected directly to a battery or DC power source. The nSLEEP pin provides an ultra-low power mode to minimize current consumption during system inactivity. Various integrated protection features safeguard the device against system faults. These protection features include UVLO, charge pump undervoltage (CPUV), overcurrent protection (OCP), and thermal shutdown (TSD). Fault conditions are indicated via the nFAULT pin.
