1. Describe
The DRV8876NPWPT is an integrated motor driver with an N-channel H-bridge, charge pump, and protection circuitry. The charge pump improves efficiency by supporting N-channel MOSFET half-bridge and 100% duty cycle drive. This family of devices 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 of the internal circuitry. Internal protection features include power supply undervoltage lockout, charge pump undervoltage, output overcurrent, and device overtemperature. Fault conditions are indicated on nFAULT. Check out our complete portfolio of brushed motor drivers on ti.com. It operates from a voltage range of 4.5 to 37V and supports various output load currents for various types of motors and loads. These devices integrate an H-bridge output power stage that can operate in different control modes set by the PMODE pin setting. This allows driving a single bidirectional brushed DC motor, two unidirectional brushed DC motors, or other output load configurations. These devices integrate a charge pump regulator to support more efficient high-side N-channel MOSFETs and 100% duty cycle operation. These devices operate from a single power input (VM) and can be connected directly to a battery or DC voltage source. The nSLEEP pin provides an ultra-low power mode to minimize current consumption during system inactivity. Various comprehensive protection functions protect equipment in the event of system failure. These include undervoltage lockout (UVLO), charge pump undervoltage (CPUV), overcurrent protection (OCP), and thermal shutdown (TSD). Fault conditions are indicated on the nFAULT pin.
