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 tran-
sistor or CPU/GPU build-in thermal diode. It requires
only let pin SET0 and SET1 tie to GND, VCC or float-
ing 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 se-
lectable to 2°C or 10°C.
