DESCRIPTION
The A5947-B three phase motor driver IC incorporates
sensorless sinusoidal drive to minimize vibration for a wide
variety of fan applications. Sensorless control eliminates the
requirement for Hall sensors.
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 A5947-B is available in a 20-lead TSSOP with exposed
thermal pad (suffix LP).
