DESCRIPTION
The A89332-1 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.
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 A89332-1 is available in a 26-contact 4 mm × 4 mm QFN
with exposed power pad (suffix EX).
