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
