Dear all,

Can a built-in NTC be used for Tj read out during operation?

Thanks in advance.

Hi Gyro Gearloose,

The data obtained from an NTC is suitable only for steady state operation control.
Transient phenomena, like heat generated in short circuit conditions, can not be monitored or detected as the correlating time constants are far too small.
For more details please read this AN.
