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)
