Hello
My customer use bq24190.
They set as:
VBAT_OVP= 1.04 x VBAT_REG =1.04 x 4.2V=4.368V
Anyway, customer use battery pack which use protection IC ( Ricoh R5478N) in the battery pack whose protecion voltage is 4.25V.
It means battery pack side (R5478N: 4.25V) protect from overvoltage faster than chargeer side (bq24190: 4.368V).
Customer's question is "is it reasonable?"
I recommend customer that it should be reasonable because pack side has lower impedance to battery , so pack side should be faster.
Would you please give us your opinion?
Best Regards
