A89332-3 controller equivalent, three-phase sensorless fan controller.
* Closed-loop speed control
* Power loss brake
* AC Loss IBB control
* Fault mode brake
* Configurable rotor detect (RD) or frequency generator
(FG) o.
A flexible, closed-loop speed control system is integrated into the IC. An EEPROM is used to tailor the common function.
The A89332-3 three-phase motor controller incorporates a sensorless sinusoidal drive to minimize vibration for highpower, high-speed server fans. Sensorless control eliminates the requirement for Hall sensors for server fan applications.
