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.  The user configurable startup, speed setting and proportional/integral (PI) control coefficients, make LV8961 suitable for a wide range of motor- and load combinations.  With a built-in linear regulator for powering an external circuit and a watchdog timer, the LV8961 offers a very small system solution. A one-time programmable (OTP) non-volatile memory in addition to RAM and an SPI interface is provided for parameter setting and monitoring of the system status. With the operating junction temperature tolerance up to 175°C , the LV8961 is an ideal solution for stand-alone automotive and industrial BLDC motor control systems.
