LM46000: spec of Tcase(max)?

Hi Jim,

The temp difference between T_junction and T-case depends on the IC power loss, so there is no spec for T-case.

ψJT Junction-to-top characterization parameter is 0.8C/W, IC power loss normally below 1.5W, so Tcase is almost same as T-J with difference <1.2C.

Hi Andy,

Thanks for reply.

One more question, in datasheet thermal shutdown threshold is typical 160 degreeC but recommandded max junction temp. is 120 degreeC.

How is the device going if the junction temp. is between 120~160 degreeC?

Or the thermal sense inside the device is not to sense junction temp.?
