Product: TLE4296-2G V50

Looking for current thresholds for the Current Limit and the Short Circuit limit. (Overload Protection).

Also looking for the temperature thresholds for thermal shutdown and recovery. (Overtemperature Protection)

 

Would be nice if someone could provide this information.

Hello,

Infineon’s automotive linear regulators are designed to withstand junction temperatures up to 150°C.

To prevent IC damage in fault conditions (e.g. output continuously short-circuited), a thermal shutdown has been integrated. The circuitry switches off the power stage for a junction temperature higher than 151°C, typically 175°C, unless otherwise specified in the datasheet. The device re-starts automatically after cooling down with a typical hysteresis of 15K (e.g. with a thermal shut-down at 175°C, re-start occurs at 160°C). 

Please refer to the below document under the chapter "Embedded Protection"->Thermal Shutdown.

Hello, 

Overload protection starts with 30mA output load current. 
Hence it is safe to operate in applications where the load current is lower than 30mA. 

The safe operating junction temperature is up to 150C. I am checking internally for the thermal shutdown limit. 
I shall come back to you once I have this information. 

Regards 
Vishnu N
