Octave Remote Resistor-programmable Temperature Switches AP2602
Preliminary Datasheet
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.

Note 2: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to
the device. These are stress ratings only, and functional operation of the device at these or any other conditions
beyond those indicated under “Recommended Operating Conditions” is not implied. Exposure to “Absolute
Maximum Ratings” for extended periods may affect device reliability.
