Part Number: BQ24196

Hi,

I want to know the quiescent current through BATFET when high-z mode is disabled and no VBUS, while the BATFET is on.

Is there any big difference for the quiescent current between disabling and enabling high-z mode?

Shubiao,

Disabling/Enabling Hi-Z mode with no VBUS attached and BATFET enabled has no significant impact on the IBAT current.

In the lab I am seeing ~34 uA of IBAT current in the configuration you described above regardless of whether or not Hi-Z is enabled. This matches the expected behavior for the device.

Thanks,

Ricardo
