The TMP139 is a high-accuracy temperature sensor with an I 2C / I3C compliant digital interface supporting In Band Interrupts (IBI). Supporting the interface requirements of JEDEC JESD302-1 for Grade-B devices, the TMP139 exceeds the temperature accuracy requirements of the specification, enabling higher performance DDR5 memory modules. Available in a compact 6-ball DSBGA package, TMP139 is designed for high-speed, high-accuracy and low-power thermal monitoring applications.

The TMP139 has a typical accuracy of ±0.25°C over the entire temperature range from –40°C to +125 °C and offers an on-chip 11-bit analog-to-digital converter (ADC) providing a temperature resolution of 0.25°C.

The TMP139 is designed to operate from a core power supply of 1.8 V and I/O power supply of 1 V, with a low typical average quiescent current of 8.3 µA when performing conversions every 125 ms.
