UCC21750: LOGIC INPUTS — IN+, IN– and RST/EN leakage current

Tool/software:

Hello everyone,

In the data sheet, the leakage current of IN+, IN- and RST/EN is specified as 90µA.

Is this leakage current caused by the internal pull-up or pull-down resistors? For example 5V/55kOhm = 90.9µA...

Thanks

Andreas
