Overview
Electric ｆans continue to sell at a steady pace, despite the widespread use of air conditioners because they use less electricity than air conditioners and provide "a natural breeze that is better for our health". Recently, high-end fan models have begun to appear with features such as remote controls for more convenient operation and automatic control of the air volume for greater comfort.
Renesas offers microcontrollers such as the 179K Series which are ideal for remote control function, the 78K0/Kx2 and the R8C Family which are ideal for the system control, and TRIACs and photocouplers for peripheral components. We offer the best solutions for developing electric fans.
