General Description

The G707 is a fully integrated, programmable remote thermal diode temperature switch with a threshold set by pin-strapping SET0 and SET1. The remote diode is a diode-connected transistor typically low-cost, easily mounted 2N3904 NPN type, 2N3906 PNP type transistor or CPU/GPU build-in thermal diode. It requires only let pin SET0 and SET1 tie to GND, VCC or floating to set the temperature threshold within a 60°C to +124°C temperature range. The G707 provides an open-drain, active low output. This switch operates with a +3.0V to +5.5V single supply while providing a temperature threshold accuracy of ±1.0°C (TYP) or ±3.0°C (max, +60°C to +100°C). Hysteresis is pin selectable to 2°C or 10°C.
