RT8749 controller equivalent, digital single-phase full wave bldc fan controller.
including the peak-current limit, thermal shutdown protection, under-voltage protection and motor lock protection. An automatic restart circuit is designed to rotate the.
By integrating a low RDS(ON) power MOSFET, the RT8749 minimizes component count on the PCB, thus reducing board size an.
The RT8749 is a highly integrated digital control IC for regulating single-phase full wave brushless DC (BLDC) fans at a programmed speed. The controller IC accepts a Pulse-Width Modulated (PWM) signal provided by the host, and decodes the duty-ratio.
