Other Parts Discussed in Thread: BQ25672, , USB2ANY
Tool/software:
Hi,
I have found that the quiescent current for the mode IQ_BAT_ON (first line in the table from section 7.5 "Electrical characteristics" page 8 of the BQ25672 datasheet) is too high.
I am measuring 58uA, but the typical figure shown the datasheet is 17uA (up to 24uA maximum).
My setup is the BQ25672EVM, attached to a Windows PC via a USB2ANY adapter, and using the TICHARGER web GUI.
The jumpers are set up as per the diagram on the Home page of the TICHARGER GUI, but with JP30 removed to prevent a extra 2mA quiescent from the I2C LDO/pull-ups.
I have successfully measured several of the the other quiescent figures in the table (IQ_BAT_OFF, ISD_BAT, IQ_VBUS), and they match the datasheet, so my hardware setup is good.
I believe I have matched the test conditions described in the datasheet.
Please can someone confirm the test conditions/register configuration for this IQ_BAT_ON quiescent current with the BQ25672EVM?
Many thanks
Rob
