Description:

GD30TS302T is a high-precision, low-power digitaltemperature sensor compatible with SMBus and I2Cinterfaces. Up to two remote diode-connectedtemperature zones can be monitored simultaneously inaddition to the local temperature.GD30TS302T features series resistance cancellation,pro-grammable η factor correction, β value detectionand automatic compensation, and programmable temperature thresholds, providing a reliable temperaturemonitoring solution with high accuracy and low powerconsumption.GD30TS302T is especially suitable for temperaturemeasurement using remote transistors (NPN / PNP Type)in servers and processors integrated in advancedprocesses. GD30TS302T supports automaticcompensation of transistor-connected PNP(0.09<β<21.36) to achieve high-precision temperaturemeasurement.The typical accuracy of GD30TS302T’s local and remotechannel is ±1°C. GD30TS302T provide a measurementresolution of 0.0625°C and a measurement range of -55°C~150°C. GD30TS302T are available in3.0mm×3.0mm, 10 pin MSOP and 3mm × 3mm, 10 pinDFN packages.
