DATA SHEET www.onsemi.com Sensorless Three-phase BLDC Motor Controller and Predriver, Automotive LV8907UW Overview The LV8907 is a high performance, sensorless three−phase Brushless DC (BLDC) motor controller with predrivers for automotive applications. An integrated two−stage charge pump provides gate current for a wide range of ultra low RDS(ON) 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 with user configurable startup, speed setting and proportional/integral (PI) control coefficients, making it suitable for a wide range of motor and load combinations.
