Description:
Three-phase sensorless fan driver.
TheA5931 three-phase motor driver IC incorporates sensorless sinusoidal drive to minimize vibration for high speed server fans.
Sensorless control eliminates the requirement for Hall sensors for server fan applications.
A flexible closed-loop speed control system is integrated into the IC.
