BCD Semiconductor Manufacturing Limited AP2602
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.GENERAL DESCRIPTION
These switches operate with a 2.7V to 5.5V single supply. The AP2602 are available in 16-pin QFN-3X3-16 package. AP2602FEATURES
