TEMPERATURE SWITCH IC WITH LATCH
S-8130AA Series
The S-8130AA is a temperature switch with a latch
function having a built-in semiconductor temperature
sensor with the accuracy of ±2.5°C. 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-8130AA 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 are enclosed in
8-Pin MSOP package.
Since the temperature range of this IC is
−40
to
+100
°C,
it is possible to achieve the extensive application for
temperature control.
