Temperature Switch with Latch
S-8130AC
The S-8130AC is a temperature switch with a latch function having a built-in semiconductor temperature sensor. The output signal is inverted when the temperature is detected, and latched until a reset signal input or a detection of the power voltage lowering. Low voltage operation down to 2.2 V is possible and the current consumption is low, 15 µA (typ.), due to CMOS configuration. The S-8130AC consists of a temperature sensor having the temperature coefficient of -13 mV/°C, a reference voltage source, a comparator, voltage detection circuit, and noise suppression circuit all of which is enclosed in a small 8-Pin MSOP package. Available temperature range is between -40 to +100 °C and wide application in temperature control can be achieved since the output linearity is excellent compared to other sensors including thermistors.
