Warm-water bidet toilet seats


In addition to basic features such as cleansing and drying using a nozzle and heating up the seat, warm-water bidet toilet seats offer an increasing range of features such as deodorizing, automatic lifting and lowering of the toilet lid and seat, and play back of camouflaging sounds and music.

At the same time,they are also required to be more energy-efficient and compact.

Our ultra-low-power-consuming microcontrollers that incorporate a wealth of peripheral functions meet these needs perfectly.

We also provide an extensive lineup of motor drivers, operational amplifiers, and photocouplers.
