BQ25600D: Quiescent current

Takashi Yamaguchi

Part Number: BQ25600D
Other Parts Discussed in Thread: BQ25619

Hi team,

My customer is evaluating the bq25600D. Could you support the following question form the customer?

The d/s specifies the IBAT(Quiescent current) as 58uA(typ) at HIZ Mode(Battery discharge mode). Customer feels the 58uA is too high for their application. If there is any way to reduce the IBAT(Quiescent current), could you tell me it?

Regards,

Yamaguchi

Yamaguchi,

The customer may disable BATFET or try BQ25619 at http://www.ti.com/product/BQ25619.

Thanks,

Ning.

Hi Ning-san,

Thank you for the answer. Could you support the additional questions below from the customer?

(1). Is the quiescent current of bq25600D at ship mode 17uA(typ), 33uA(max)?

(2). Is there a way to enable the BATFET other than the following four ways?

1. Plug in adapter

2. Clear BATFET_DIS bit

3. Set REG_RST bit to reset all registers including BATFET_DIS bit to default (0)

4. A logic high to low transition on QON pin with tSHIPMODE deglitch time to enable BATFET to exit shipping mode

(3). If you have a comparison table between bq25600D and bq25619, could you send me it? Customer wants to know the difference.

Regards,

Yamaguchi
