S-5842A Series DUAL TRIP TEMPERATURE SWITCH IC (THERMOSTAT IC) www.sii-ic.com SII Semiconductor Corporation, 2008-2015 Rev.2.3 01 The S-5842A Series is a dual trip temperature switch IC (thermostat IC) which detects two points of temperature. The S-5842A Series operates at the power supply voltage of 2.5 V and the lower current consumption of 10 A typ. A temperature sensor with the negative temperature coefficient, a reference voltage generation circuit, a comparator and a delay circuit are integrated on one chip, and enclosed into the packages SOT-23-6 and SNT-6A. Features Detection temperature: Detection temperature = 10C to +110C, +1C step Accuracy of detection temperature: 2.5C (Only for either detection temperature) Low voltage operation: VDD = 2.5 V min. (Detection temperature = +20C to +110C) VDD = 2.7 V min. (Detection temperature = 0C to +110C) VDD = 2.8 V min. (Detection temperature = 10C to +110C) Low current consumption: IDD = 10 A typ. (Ta = +25C) Selectable output form: CMOS output, Nch open-drain output Selectable output type: Separate, Integrate Selectable output logic: , Operation temperature range: Ta = 40C to +125C *1 Lead-free, Sn 100%, halogen-free *1.
