INA228-Q1: The input current of VBUS pin under current measurement mode
For the INA228, the VBUS input impedance is typically 1MΩ when in active mode (which is during either VBUS measurement or Current Measurement). And then changes to high impedance (with the 10nA leakage current at VBUS=85V) during shutdown mode. The specific impedance is not specified.
If you are looking for a device that only has the higher current draw on VBUS pin when doing a VBUS measurement, but changes to high impedance during both shutdown and current measurement mode, then you may be interested in one of these devices:
