Description

The DRV8874 is an integrated motor driver with N-channel H-bridge, chargepump, current sensing and proportional output,current regulation, and protection circuitry. The charge pump improves efficiency bysupporting N-channel MOSFET half bridges and 100% duty cycle driving. The family of devices come inpin-to-pin RDS(on) variants to support different loads with minimal designchanges.

An internal current mirror architecture on theIPROPI pin implements current sensing and regulation. This eliminates the need for a large powershunt resistor, saving board area and reducing system cost. The IPROPI current-sense output allowsa microcontroller to detect motor stall or changes in load conditions. Using the external voltagereference pin, VREF, these devices can regulate the motor current during start-up and high-loadevents without interaction from a microcontroller.

A low-power sleep mode achieves ultra-low quiescent current draw by shutting down most ofthe internal circuitry. Internal protection features include supply undervoltage lockout, chargepump undervoltage, output overcurrent, and device overtemperature. Fault conditions are indicatedon nFAULT.
