D16 Schottky diode inverted?

Open LorenzoGuerro opened this issue 1 year ago • 2 comments

Hello,

I simulated the reverse polarity protection circuit and it somehow doesn't work. There is a whole amount of current flowing over the DSG pin through the Schottky diode D16 with a reversed charger. A Texas Instrument application document shows this diode inverted. Is not the R51 68k resistor meant to drive the gates and the (then inverted) diode to turn off the discharge MOSFETs faster?

Then, if there is a reversed charger connected, voltage drops over the R51 68k resistor.
