Other Parts Discussed in Thread: BQ24610, BQ40Z50, EV2400, LM25116, LM34936
Hi guys,
I made a drawing of the strange case we get on a BQ40Z50R1 + BQ24610 design.
We have 2 version of MotherBoard using 2 types of power architecture to generate 3v3, 12v and 5v
One of them (our new motherboard design) have a strange behaviour when reading data from BQ40Z50R1.
Charging and discharging the battery works well, system is correctly powered from battery but the data read from BQ40Z50 are not relevant
Using EV2400,
Current displayed = 0 when battery is discharging (remenber: battery powered correctly the system)
Current displayed = 20mA when battery is charging. (remenber battery is correctly charged after 2 hours)
and others parameters are also not relevant :
For example : 'time to full' is very long (because current charge is 20mA) But in real , current charge is 1.6A
I can provide schematics of the 3 systems
Any idea to help ?
Regards
Gilles
