Other Parts Discussed in Thread: BQ40Z50
Hi all,
I work with a BQ40z60 EVM.
We use a 4 cells pack @ 3350mAh to provide power to a PC like with DLP projector embedded.
So we have 2 main state of working phase for the BQ40z60
1) PC is OFF, Power supply ON, BQ40z60 can charge the battery if necessary. The current value is 1625mA. --> Works well
2) PC is ON, (current needed by PC is 2A). If the current still set to 1625mA, battery does not charge. If I set the current to 3625mA, the battery charge at 1625mA
I don't really understand the notion of 'charging current' in the datasheet !
As I see, the charging current is the total current use by the system, not the one needed by the battery !
Am I wrong ?
If no, do we need to monitor the current charge as describe above ?
or do we have an another way to do it automatically ?
Other question :
On the firmware R3 of BQ40z50, there is a new function to use the LED/GPIO as single GPIO (to on-off a led)
Do you expect to do same function on firmware of the BQ40z60 ?and when ?
Regards
Gilles
