Part Number:BQ25895
I have a few questions regarding the BQ25895:
1) Does the BQ25895 retain the programmed settings after a power cycle and the host processor is not present? Device is turned off, but the battery needs charged.
2) How does the BQ25895 negotiate current without the use of the CC signals? Everything I read indicates that the CC signals are required for the higher currents. I suspect that D+/D- will only negotiate to 500mA. I need 3A.
3) Can the BQ25895 be on the D+/D- signals along with the processor that is receiving the data? Will that create signal contention? Do I need to use a switch instead? Recommendations?
