Description:

GD30TS308T is a high-precision, low-power digital temperature sensor compatible with SMBus and I2C interfaces. In addition to the local temperatureof the chip, up to 8 remote diode areas can be monitoredsimultaneously. The typical application scenario ofGD30TS308T is real-time remote temperaturemonitoring of complex systems such as MCU, GPU andFPGA. With functions such as series resistanceelimination, programmable η factor correction,programmable temperature offset correction andprogrammable temperature threshold, GD30TS308Tprovides a reliable temperature monitoring solution withhigh precision and low power consumption.

The local channel and 8 remote channels ofGD30TS308T can be independently programmed andcontrolled. When the temperature of the measuredlocation exceeds the corresponding temperaturethreshold, an alarm will be triggered. Each channel ofGD30TS308T has a programmable temperaturethreshold hysteresis setting to avoid repeated alarmscaused by the measured temperature being near thetemperature threshold.The typical temperature measurement accuracy of thelocal channel and remote channel of GD30TS308T is±0.5°C and ±1°C respectively, and both provide atemperature measurement resolution of 0.0078125°Cand a temperature measurement range of −55°C to+150°C. The power supply voltage range of GD30TS308is 2.7V to 5.5V, and it provides 3.00mm×3.00mm 16 PinQFN package for integration into various systems.
