DATA SHEET www.onsemi.com Sinusoidal Sensorless Three-Phase Brushless DC Motor Controller and Predriver LV8961HUW Overview The LV8961 is a high performance sinusoidal sensorless three−phase BLDC motor controller with predrivers for automotive applications. An integrated two−stage charge pump provides gate current for a wide range of ultra low Rdson NFETs. The device offers a rich set of system protection and diagnostic functions such as overcurrent, overvoltage, short−circuit, undervoltage, overtemperature and many more. It supports open−loop as well as closed−loop speed control based on Back ElectroMotive Force (BEMF) observation.
