A5947G Three-Phase Sensorless Fan Driver

The A5947G three phase motor driver IC incorporates sensorless sinusoidal drive to minimize vibration for a wide variety of fan applications. Sensorless control eliminates the requirement for Hall sensors. A flexible closed-loop speed control system is integrated into the IC. EEPROM is used to tailo.

A5947G Features

* Speed curve configuration via EEPROM

* I2C serial port

* Sinusoidal modulation for reduced audible noise and low vibration

* Sensorless (no Hall sensors required)

* Low RDS(ON) power MOSFETs

* 3.3 V / 20 mA linear regulator

* PWM or analog sp
