3 Description
The DRV10964 is a three-phase sensorless 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 sensorless windowless
180° sinusoidal control scheme offers ultra-quiet
motor drive performance. The DRV10964 contains an
intelligent lock detect function, combined with other
internal protection circuits to ensure safe operation.
The DRV10964 is available in a thermally efficient 10-
pin USON package with an exposed thermal pad.
