Beschreibung

KI-Übersetzung

The A5947G 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 A5947G is available in a 28-contact 5 mm×5 mm QFN with exposed thermal pad (suffix ET) and a 20-lead TSSOP with exposed thermal pad (suffix LP).
