General Description
The AP2602 are fully integrated, resistor
programmable octave remote temperature switches
with selectable external/internal trigger voltages
setting. The thresholds are set by external resistors
and thermistors with negative temperature
coefficient.
The AP2602 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 AP2602 are available in 16-pin QFN-3X3-16
package.
