Temperature Monitor

The Temperature Monitor is a fully integrated analog IP supervising the junction temperature (TJ) of the device.



Fully integrated
Small area & low power
Trimming at room temperature
Accurate trimming
Silicon proven


Fully-integrated analog IP monitoring the junction temperature (TJ)
Two active-high alarm signals:

  • one alarm signal indicating that TJ < TJ_low
  • one alarm signal indicating that TJ > TJ_high

Two trimming methods of the temperature detection thresholds:

  • ±1.5°C accuracy method requiring temperature steps at TJ_low and TJ_high
  • ±5.0°C accuracy method involving only one step at 25°C

Operating junction temperature range: -40°C to 125°C
Minimum/maximum nominal values of the accurate trimming method:

  • min(TJ_low) = -38.5°C
  • max(TJ_high) = 123.5°C

Minimum/maximum nominal values of the ambient trimming method:

  • min(TJ_low) = -35.0°C
  • max(TJ_high) = 120.0°C

Power-supply voltage range: nominal core voltage ±10%
Typical characteristics of a 65 nm CMOS implementation:

  • wake-up time shorter than 50 µs
  • operating current smaller than 50 µA
  • standby current lower than 40 nA
  • silicon area smaller than 0.04 mm²

Silicon proven in 130 nm, 110 nm, 65 nm and 55 nm CMOS processes
