| Description | Digital Single-Phase Full Wave BLDC Fan Controller |
|
|
The RT8749A is a highly integrated digital controlled predriver 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. The decoded duty-ratio will then be used for mapping to the programmed speed which is stored at the embedded flash memory.
