LV8907UW Sensor-less Three-phase Brushless DC Motor Controller, with Gate Drivers, for Automotive www.onsemi.com Overview 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 SPQFP48 7x7 R type external N-MOSFETs. The device offers a rich set of DS(ON) CASE 131AN system protection and diagnostic functions such as over-current, over-voltage, short-circuit, under-voltage, over-temperature and many MARKING DIAGRAM 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 LV8907 YMALN Network) transceiver, the LV8907 offers a very small system solution. The LV8907 stores system parameters in embedded one-time programmable (OTP) non-volatile memory in addition to RAM system memory. An SPI interface is provided for parameter setting and monitoring the system status. With the operating junction Y = Production Year temperature tolerance up to 175C and electrically LIN compatible M = Production Month control signals (PWM and Enable), the LV8907 is an ideal solution for A = Assembly Start Week stand-alone BLDC motor control systems.
