DUAL TRIP TEMPERATURE SWITCH IC
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 μA 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.
