Hello,
I am designing the circuit used TPS1H200A-Q1.
I am considering a circuit that connects a optocoupler to the /FAULT pin of TPS1H200A-Q1 to interface with the host controller.
I couldn't find any specifications for this /FAULT pin leakage current in the data sheet.
I estimate the value of the leakage current to be several microamperes.
I think it is unlikely that this leakage current will drive the LED with a built-in optocoupler, but if possible, I would like to confirm the value of this leakage current.
Regards, MESH
