TCAN1043A-Q1: Leakage Current Definition

Part Number: TCAN1043A-Q1

Hi team,

The EN and nSTB pins, it says that there's an internal pulldown to ensure the device stays in the proper off-state. When looking at the leakage current for EN and nSTB, does leakage current figures in the datasheet account for IA+IB or is the leakage figure in the datasheet only account for IA as drawn below?

Thanks,

Jacob

    Hi Jacob,

    Yes, the leakage current specification includes all current into the pin. So this includes IA and IB in your drawing. Note that IA will be relatively very small because it is a digital input pin with minimal leakage compared to an internal pull-down bias.
