Part Number: BQ24725A
I'm looking to update a design that uses a 4 cell Li Ion, 14.8V, 2.6Ah battery. Max charge 1.9A CC, 16.8V CV.
Point of concern is the higher current consumption of BQ24725A when the system is powered from battery, but shutdown.
A small amount of battery current is still required by the system (100uA).
Is it correct that in order to match the battery drain current (5uA) of BQ24617, I would have to disconnect BQ24725A from the battery as shown in figure 18 of the datasheet?
Can BQ24725A at least match the same diagnostic features of BQ24617, using the SMBus rather than the STAT1, STAT2 & PG output pins.
Plan would be to marry the BQ24725 with a BQ40Z50 in the battery pack.
Thanks,
Andy.
