Hi,

When customer does not need "reverse current protection" and "reverse insertion protection (negative voltage protection)" on LM74900-Q1, does NOT they need "FET connected with DGATE" ? Please let us know.

Thanks and best regards,

Hi Hatorri,

Welcome to E2E.

If reverse current blocking and reverse polarity protection are not required, it seems you only require blocking FET features like over voltage, undervoltage protection, over current and short circuit protection?

Please consider Hotswap controllers or high side switch controllers.

Or please list down required features and power rating for me to recommend a device
