... Accurate internal overtemperature protection is provided in the TEA1713LT. When the junction temperature exceeds the overtemperature protection activation temperature, T (typ. 150 C), the IC will go to the Thermal hold state. The TEA1713LT will exit the Thermal hold state when the temperature falls again, to around 10 C below T ...

... A low-load condition can be detected using a simple external circuit that makes use of the information from the feedback loop or from the average primary current. The detection circuit can pull down pin SNSOUT to pause operation of the TEA1713LT for a burst-off time. Both controllers, or only the HBC controller, can be paused during the burst-off time: • ...
