3 . Chip Overview
The GXTR31X1 series is a high-precision, low-power digital temperature sensor compatible with SMBus and I2C interfaces. In addition to the local temperature where the chip is located, up to 1 (GXTR3111)/2 (GXTR3121) remote temperature probes can be monitored simultaneously for remote temperature in the area where they are located.
The GXTR31X1 series has functions such as series resistance elimination, programmable η factor correction, β value detection and automatic compensation, and programmable temperature threshold, providing a high-precision, low-power and reliable temperature monitoring solution. The GXTR31X1 series is particularly suitable for temperature measurement using remote transistors (NPN/PNP Type) integrated into servers and processors under advanced manufacturing processes. The GXTR31X1 series supports compensation for PNP with 0.09<β<21.36 and transistor connections to achieve high-precision temperature measurement.  
The typical temperature measurement accuracy values for the local and remote channels of the GXTR31X1 series are ± 0.5 ° C and ± 1 ° C, respectively, and both provide a temperature measurement resolution of 0.00390625 ° C and a temperature measurement range of -55~+150 ° C. The GXTR31X1 series has a power supply voltage range of 2.7~5.5V and offers a 3mm x 3mm 8/10 pin MSOP package for integration into various systems.
