Japan Seiko Instruments Announced New Temperature Sensor IC Optimized for LED Lighting

Japan Seiko Instruments Inc. (SII) has introduced the S-5855A Series, a PWM output temperature sensor IC for LED lighting designs.

The new product begins to decrease the duty ratio of PWM signal output when the temperature exceeds the specified value, thus enables LED lighting circuits to avoid temperatures increasing above design limits, improving safety and efficiency while reducing total design cost. The S-5855A is connected to the DIM pin of an LED driver IC to control the LED luminance, enhancing safety protection and boosting efficiency.

It is optimized for use in LED lighting systems for PC laptops, tablets and other devices. It can also be used with any system requiring temperature control.
