DRV8876N

Datasheet spin for DRV8876 without current sense

描述

The DRV887x family of devices are flexible motor drivers for a wide variety of applications. The devices integrate an N-channel H-bridge, charge pump regulator, and protection circuitry. The charge pump improves efficiency by allowing for both high-side and low-side N-channels MOSFETs and 100% duty cycle support. The family of devices come in pin-to-pin, scalable RDS(on) options to support different loads with minimal design changes.

A low-power sleep mode is provided to achieve ultra-low quiescent current draw by shutting down most of the internal circuitry. Internal protection features are provided for supply undervoltage lockout (UVLO), charge pump undervoltage (CPUV), output overcurrent (OCP), and device overtemperature (TSD). Fault conditions are indicated on nFAULT.
