Preliminary Datasheet

Octave Remote Resistor-programmable Temperature Switches AP2602

Feb. 2012 Rev. 1. 0 BCD Semiconductor Manufacturing Limited

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.
