Note:
Temperature sensor output
The STCN75 Temperature Sensor has a dedicated open drain overlimit 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 STCN75 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
