Overview - S-5840B series
Temperature Switch IC with Latch S-5840B series
The S-5840B Series is a temperature switch IC with a latch function having a built-in semiconductor temperature sensor with an accuracy of ±2.5°C. The output signal is inverted when the detection temperature is reached, and latched until detection of the power supply voltage lowering.
Low voltage operation down to 1.0 V is possible and the current consumption is low, 12 µA (typ.), due to CMOS configuration. The S-5840A Series consists of a temperature sensor with negative temperature coefficient, a reference voltage source, a comparator, voltage detection circuit, and noise suppression circuit, all of which are enclosed in SOT-23-5 package.
Since the temperature range of this IC is -40 to +100°C, it is possible to achieve the extensive application for temperature control.
