TPS2595: Diodes for protection

Hideki Hayashi1

Part Number: TPS2595

Hi team,

Is customer able to add diodes to prevent below?

1. Reverse current blocking: Is it ok to add diode to prevent it?

2. Reverse polarity: Is it ok to add Schottky on input? If it works, Vin would be < -0.3V.

BEst regards,

Hayashi

    Hi Hayashi San,

    1. Diodes can be used for reverse current blocking.

    2. No, that will violate the abs minimum, and I suggest you use back-to-back FET configuration for reverse polarity protection. 

    You can use integrated solutions like 25947. They also have back-to-back FET configuration which is required for reverse polarity and also have reverse current blocking.

    Best Regards,
