LV8968BBUW Multi-purpose BLDC Gate-driver for Automotive Overview The LV8968BB is a 3 phase BLDC/PMSM pre driver with integrated phase voltage sensing and logic level FET compatibility.

The wide operating voltage range and AEC Q100 qualification make this device ideal for automotive applications.

Six gate drivers provide 400 mA (typ) gate current to external power bridges allowing use of low resistance power FETs as well as logic level FETs.

All FETs are protected agains
