A89331 3-Phase Sensorless Fan Drivers

Allegro MicroSystems A89331 3-Phase Sensorless Fan Drivers incorporate sensorless sinusoidal drives 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. An EEPROM tailors 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 A89331 is available in a 28-lead 5mm × 5mm QFN with an exposed power pad (suffix ET) and a 20-lead TSSOP with an exposed power pad (suffix LP).
