DRV10964 Three-Phase Sensorless Motor Driver

Texas Instruments offers its DRV10964, 5 V, three-phase, sinusoidal, sensorless, BLDC motor driver for notebook CPU fans, game station CPU fans, and ASIC cooling fans

Image of Texas Instruments' DRV10964 Three-Phase Sensorless Motor DriverTexas Instruments' 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.
