LV8961HUWR2GEVK

LV8961HUWR2G evaluation kit is used to evaluate LV8961HUW IC. The LV8961H 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 start-up, 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 and a watchdog timer, the LV8961H offers a very small system solution.
