AM620-Q1: What's the recommend temperature sensor threshold for automotive application?

Part Number: AM620-Q1


Tool/software:

Hi, Dear Expert

We already know our SDK support "Voltage & Thermal Management" (VTM).

reference as below

	main1_thermal: main1-thermal {
		polling-delay-passive = <250>;	/* milliSeconds */
		polling-delay = <500>;		/* milliSeconds */
		thermal-sensors = <&wkup_vtm0 1>;

};

This question is from customer, and post here for double checking.

Base on "automotive" ECU application, do you think what's the good "temperature threshold value setting" for main0-crit & main1-crit?

Thank You Very Much
