S-5855A Series www.sii-ic.com © Seiko Instruments Inc., 2010-2013 PWM OUTPUT TEMPERATURE SENSOR IC Rev.1.2_00 The S-5855A Series, developed by CMOS technology, is a 1-wire PWM output temperature sensor IC of low current consumption that itself changes the duty ratio according to temperature.

The duty ratio decreases from 100% if exceeding the temperature set by user, and this decrease is linear against the temperature rise.

The output form is selectable from CMOS output and Nch open-drain out
