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. Features 8 Remote Temperature Switches Set by Thermistor and External Resistors 4 Open-drain Active Low Output Stages for Each 2 Temperature Switches Selectable External/Internal Trigger Voltages Setting Built-in Hysteresis Temperature when Using Internal Setting Trigger Voltage Guaranteed Output Signal Valid to =0.8V QFN-3X3-16 Package Applications µp Temperature Monitoring High-speed Computers Temperature Control Temperature Alarms Fan Control Automotives QFN-3X3-16 Figure 1.
