Description

The LV8907 is a high performance, AEC−Q100 qualified,sensor−less three−phase BLDC motor controller with integrated gate drivers for driving external N−MOSFETs. An on−chip two−stage charge pump provides required gate voltage for a wide range of low RDS(ON) type external N−MOSFETs. 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 a built−in linear regulator for powering external circuits, a watchdog timer, and a LIN (Local Interconnect Network) transceiver, the LV8907 offers a very small system solution.The LV8907 stores system parameters in embedded one−timeprogrammable (OTP) non−volatile memory in addition to RAMsystem memory. An SPI interface is provided for parameter setting and monitoring the system status. 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.
