Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The A5947KLPTR-B-T three-phase sensorless fan driver IC contains a sensorless sine wave driver that minimises vibration in a variety of fan applications. The device's sensorless control eliminates the need for Hall sensors. The device also incorporates a flexible closed-loop speed control system. an EEPROM is used to match the standard functionality of the fan speed profile to a specific application, eliminating the need for a microprocessor-based system while minimising programming requirements.
