DESCRIPTION

DRV11873 is a three phase, sensorless motor driver with integrated power MOSFETs with drive current

capability up to 1.5-A continuous and 2-A peak. DRV11873 is specifically designed for low noise and low external

component count fan motor drive applications. DRV11873 has built in over current protection with no external

current sense resistor needed. The synchronous rectification mode of operation achieves increased efficiency for

motor driver applications. DRV11873 outputs FG and RD to indicate motor status with open drain output. A 150°

sensorless BEMF control scheme is implemented for a three phase motor. DRV11873 is available in the

thermally efficient 16-pin TSSOP package. The operation temperature is specified from -40°C to 125°C.
