UART short to battery protection IC

Other Parts Discussed in Thread: TPS25947

Team,

We’re looking for a protection method or device to protect a 5V-tolerant UART bus in the event of short-to-battery (12V) condition.

May you purpose the appropriate solution to me?

    Hi Roy,

    Thanks for reaching out! 

    We have a new device TPS25947 releasing in March and preview version is available on web. It has true reverse current blocking which will quickly turn off the device when 12v is applied at its output thus isolating 5v UART bus present on input pin of this device.

    Please refer section 8.3.7 Reverse Current Protection of datasheet for more details. Datasheet link:

    Let me know any further questions.

    Regards
