Hi all.
I am trying to build battery management system fo 3S LiPol. I use IC BQ24725.
Schematic sheet is repeat datasheet. For data configuration -- EV2300.
Data:
Charge option: 0x7905
ACOK Deglitch Time -- 0( default )
WATCHDOG Timer -- 0 ( disable )
BAT Depletion Comparator -- 11( default )
EMI Switching Frequency -- 0( default )
EMI Switching Frequency Enable -- 0( default )
IFAULT_HI Comparator Threshold -- 10( default )
LEARN Enable -- 0( default )
IOUT Selection - 0( default )
ACOC Threshold -- 10( default )
Charge Inhibit -- 1
Charge Current: 0x0400( 1024mA )
Charge voltage: 0x3140( 12608mV )
Input current: 0x1000( 4096mA )
Here is problems. Than I want to begin charging( charger option 0x7904 ). It doesn`t work. The IC switchs system power from adapter to battery only.
Could you explain there problem is ?
