Temperature sensor output
The STLM75 Temperature Sensor has a dedicated open drain Over-Limit Signal/Interrupt
(OS/INT) output which features a thermal Alarm function. This function provides a user-
programmable trip and turn-off temperature. It can operate in either of two selectable
modes:
●
●
At power-up the STLM75 immediately begins measuring the temperature and converting the
temperature to a digital value.
The measured temperature value is compared with a temperature limit (which is stored in
the 16-bit (T
