Description: Digital Single-Phase Full Wave BLDC Fan Controller

Features

* including the peak-current limit, thermal shutdown protection, under-voltage protection and motor lock protection. An automatic restart circuit is designed to rotate the motor after the lock condition is released. Features
* Embedded 256 x 16 Bits Flash Memory
* Built-in Low RDS(ON) Power

Applications

* By integrating a low RDS(ON) power MOSFET, the RT8749 minimizes component count on the PCB, thus reducing board size and cost of the motor/fan module. A frequency generator output is included to provide commutation signals to the host for the current rotating speed. The control IC also provides sev
