Overview - S-5855A Series

PWM OUTPUT TEMPERATURE SENSOR IC S-5855A Series

The S-5855A Series, developed by CMOS technology, is a 1-wire PWM output temperature sensor IC of low currentconsumption that itself changes the duty according to temperature.
The duty decreases from 100% if exceeding the temperature set by user, and this decrease is linear against the temperaturerise.
CMOS and Nch open drain are available for its output form.Its small packages SNT-4A and SOT-23-5 enable high-density mounting.
