Tool/software:
Hi
If I just apply a 9V 3A (via a benchtop PSU) to VBUS input of BQ25601D with D+/D- floating, what is the charge current is going to be?
It is under the conditions that register REG00 set to its default values so, IINDPM[4:0] is 10111 (the input current limit is 2400mA.)
I am wondering if the power input will be treated as an unknown adapter following VBUS_STAT[2:0] of 500mA or, the input current limit of 2.4A will dominate.
The result will be a lot different 9*2.4W vs 9*0.5W.
Please advise.
Best regards
John Leung
