DESCRIPTION
The DRV10963 is a three phase sensor-less motor driver with integrated power MOSFETs. It is specifically designed for high efficiency, low noise and low external component count motor drive applications. The proprietary sensor-less window-less 180° sinusoidal control scheme satisfies the ultra-quiet requirement. The DRV10963 contains an intelligent lock detect function, which ensures safe operation in the event of a locked rotor. The DRV10963 is available in a thermally efficient 10-pin USON package with an exposed thermal pad.
