A5931-3 Three-Phase Sensorless Fan Driver

The A5931-3 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. EEPROM.

A5931-3 Features

* Closed-loop speed control

* Speed curve configuration via EEPROM

* Programmable deceleration time

* I2C serial port

* Sinusoidal modulation for reduced audible noise and low vibration

* Sensorless (no Hall sensors required)

* Low RDS(ON) powe
