TPS25924: Reverse current protection, protection if Vout voltage is higher then Vin when EN at enabled/disabled

Part Number: TPS25924

Dear Sir,

Refer to page 20 of TPS25924 datasheet -> Figure 43. Inrush and Reverse Current Protection.

Vin of TPS259241 will be the range of 4V~11V power rail and it will provide this power it OUT to USB-C connector to external accessory with current limit function.

Thus, it's OUT will also need over voltage protection.

Does over voltage protection also work at Vout side (as attached chart)? 

If it works -> could I use the same figure 43 to TPS259271(no detail reverse current circuit mentioned on TPS259271 datasheet), too?

Thanks.

    Hi Hugo Lee,

    Welcome to e2e !

    When you say that you require Overvoltage protection at the output, do mean that you require the overvoltage at the output not to be seen at the input ?
    Unfortunately, TPS25924x is not designed to protect the input from output overvoltages.
