Other Parts Discussed in Thread: EV2400
Hi there,
My name is Fenrir, I'm doing a charge test with BQ25892.
The problem that I face is, when the battery is 3V charging current will go down from 2A, the charger can not get in CC mode. Should I disable the ICD then try again?
Input Power = 12V/3A from power supply
Battery information:
Nominal Voltage = 3.8V
Max continuous charge current = 2A
End Voltage = 2.92V
Full Voltage = 4.2V
Thermistor = TH05-3H103FR
The inductor specification, which is L15 in schematic.
Below is register table:
REG0 = 0x7F
REG1 = 0x06
REG2 = 0x1D
REG3 = 0x1A
REG4 = 0x20
REG5 = 0x13
REG6 = 0x5E
REG7 = 0x9D
REG8 = 0x03
REG9 = 0x44
REGA = 0x73
REGB = 0x47
REGC = 0x85
REGD = 0x53
REGE = 0x00
REGF = 0x00
REG10 = 0x00
REG11 = 0xDF
REG12 = 0x00
REG13 = 0x3F
REG14 = 0x05
I don't have a EV2400, so I read I2C value from "Total Phase" then fill in the register.
