DESCRIPTION
The A89331 three-phase motor driver incorporates sensorless
sinusoidal drive 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. 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 A89331 is available in a 28-lead 5 mm × 5 mm QFN with
exposed power pad (suffix ET), and a 20-lead TSSOP with
exposed power pad (suffix LP)
