Tool/software:
Dear TI experts,
My customer checks the specification of TPS25961 for their next project.
And here is the question from my customer ;
(Cable end to the device)----------(Cable end to the adapter jig) [Adapter jig] (Cable end to the adapter jig)---------(AC Adapter)
Anyway, charging cable and AC adapter with attached cable is connected with adapter jig.
Adapter jig has just 2 connector, VCC and GND routiong. nothing else.
Recently they found that cable end to the device has dust or other foreign body so VCC and GND are shorted, And AC adapter is damaged severly as a result.
(Device is okay because they used fuse and other protection)
To prevent AC adapter damaged, They want to add eFuse like TPS25961 on the adapter jig, between 2 connectors.
But as you know, if there are any sort circuits due to dust or something else, I am worried about eFuse would damaged or not.
So I want you to confirm the things below;
1. Regarding to the EVM schematics below, Will the protection work well if VIN and GND are shorted?
2. Is it okay to connect VIN to device side and connect to VOUT to adapter side? (Then we can protect short situation from the cable end to the device.)
Best regards,
Chase
