G717 Global Mixed-mode Technology Octave Remote Resistor-Programmable Temperature Switches Features General Description 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 VCC = 0.8V TQFN3X3-16 Packages The G717 are fully integrated, resistor programmable octave remote temperature switches with selectable external/internal trigger voltages setting. The thresholds are set by external resistors and thermistor with negative temperature coefficient. The G717 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 G717 are available in 16-pin TQFN3X3-16 packages.
