General Description
The G717 are fully integrated, resistor programmable
octave remote temperature switches with selectable
external/internal trigger voltages setting. The thresh-
olds are set by external resistors and thermistor with
negative temperature coefficient. The G717 provides 4
open-drain, active low, over-temperature outputs for
each 2 sensors. These switches operate with a +2.7V
to +5.5V single supply.
The G717 are available in 16-pin TQFN3X3-16 pack-
ages.
