The LV8907 is a high performance, 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 RDS(ON) NFETs. The device offers a rich set of system protection and diagnostic functions such as over-current, over-voltage, short-circuit, under-voltage, over-temperature 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. With an in-built linear regulator for powering an external circuit, a watchdog timer and a Local Interconnect Network (LIN) transceiver, the LV8907 offers the smallest system solution footprint. An SPI interface is provided for parameter setting and monitoring the system health. With the operating junction temperature tolerance up to 175°C and electrically LIN compatible control signals (PWM and Enable), the LV8907 is an ideal solution for stand-alone BLDC motor control systems.
