Part Number: TPS25940

Hi Sir,

May I know the TPS25940 internal back to back MOSFET Ids spec and SOA curve?

Please feel free to contact me via mail.

Thank you.

    Hi Edward,

    Can you let us know why you need the internal FET parameters.

    The maximum current limit setting for this device is 5.2A which allows user to use this device for a maximum load current of 4.78 A.

    Regarding the FET SOA, the device is designed to operate always under its SOA and protect itself wit the help of Thermal Shut Down feature as long as the device is used under its recommended operating conditions.

    Hi Praveen,

    Customer would like to test short circuit test and need to make sure the current spike will not over TPS25940 Ids spec, do you think we can provide that data to them?

    Thank you.

    Hi Edward,

    Please refer this application note for detailed understanding. 

    As long as the voltage applied to the efuse is within the Recommended Operating Condition, the efuse will limit its current to a safe value and make sure the internal FET is operated under its SOA with the help of thermal shutdown. 

    So, customer need not worry about the FET SOA as we guarantee its protection under fault conditions.
