Description: Three-Phase Sensorless Fan Driver

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

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 tailor the common functions of the fan speed curve to a specific application. This eliminates the requirement for a microprocessor-based system an
