Hello Support Team,
What is the recommended method for measuring the junction temperature of the device that haven't temperature output by SMS pin?(ex.TPS1HB08F or TPS1HB16F)

Ishigami-san,
We have no specific recommendation for measuring the junction temperature for Version F devices.
A external sensor can be used to measure the junction temperature or the sns current can be converted into a approximate temperature in an MCU by calculation.
The output of the SNS pin is a fraction of the load current. I^2 * R_on (max) will provide the worst case DC power dissipation of the junction. Please not that this is just an approximation.
Thanks,
