D24V90F5 Inquiry

Hi There,

I was reading the datasheet for your voltage regulator on this board the 2101 and in their typical application diagram they don’t show the black square chip near the Vin corner of the board, is this another MOSFET? I’m just trying to understand if that is a critical component or maybe I’m looking at the wrong data sheet?

Anything helps, Thanks!


That is the reverse voltage protection MOSFET. We use a circuit similar to the one discussed in this Hackaday article.
