General Description
The G718 are fully integrated, resistor programmable
dual remote temperature switches. The thresholds are
set by external resistors and negative temperature
coefficient thermistors. The G718 provides open-drain,
active low over-temperature outputs for both sensors.
These switches operate with a +2.7V to +5.5V single
supply.
The G718 are available in 8-pin SOT-23 and
AQFN1.5X1.5 packages.
