三相正弦波无传感器风扇电机驱动器GC5958国产替代ANPEC/茂达电子 APX9358

Chip description：
The GC5958 provides all the circuitry forsensor-less speed control of three-phase brushlessDC motor. The Sine-wave Driver Method will bebetter low-noise. The controller functions includestart-up circuit, back-EMF commutation control,Pulse Width Modulation (PWM) speed control,lock protection, and thermal shutdown circuit.

The GC5958 is suitable for both game machineand CPU cooler that need silent drivers. It isavailable in DFN3x3-10 package.

Chip features：
 PWM Quasi-Sinusoidal Driver
 Three-Phase Sensor-Less Drive Method
 Adjustable Forced Commutation Frequency(for Start-up)
