Description: Three-Phase Sensorless Fan Controller

Features

* Closed-loop speed control
* Power loss brake
* AC Loss IBB control
* Fault mode brake
* Configurable rotor detect (RD) or frequency generator (FG) output
* Speed curve configuration via EEPROM
* I2C serial port
* Sinusoidal modulation

Applications

* A flexible, closed-loop speed control system is integrated into the IC. An 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 and minimizes programming requirements. The A89332-3 is availa
