S-5855A Series .sii-ic. © 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 output. Its small packages SNT-4A and SOT-23-5 enable high-density mounting. - Features - PWM output - Temperature accuracy - Duty ratio change-start temperature - Duty ratio temperature sensitivity -...
