Hello,
Someone will get back to you by next Tuesday.

Hello,
Please check out:
1. IQ_BAT, or Quiescent battery current (BATSNS, BAT, SYS, SW). This is typ 9.5 uA and max15 uA.
2. ISHIP_BAT, or Shipmode battery current (BATSNS, BAT, SYS, SW). This is typ 7 uA and max 9.5 uA.

Hi Michael,
1. IQ_BAT, or Quiescent battery current (BATSNS, BAT, SYS, SW). This is typ 9.5 uA and max15 uA.Is IQ_BAT an Ibat leakage current?
Using EVM tests are as follows:
Ibat leakage when the battery full charged.
Test condition:BAT = 4.35V(Cut-off voltage), VBUS = 5V, SCL, SDA = 0V or 1.8V, BATFET enabled ,Ibat leakage current=110uA
Why is the Ibat leakage current 110uA when Vbus=5V?
Hello,
Please check your pullups. Pullups on I2C, CE, etc. will cause leakage from the battery as well.

Hi Michael,
Using the bq25618EVM test,Ibat leakage current=110uA.Please check it.As shown below.
VBUS =4.9899V
Vbat=4.43V (Cut-off voltage)
I2C=0V
Ibat leakage current=110uA
Hello,
With battery charge voltage limit set to 4.35 V, VBAT voltage at 4.43 V (BATOVP), SDA at 0 V, and VBUS at 5.19 V the leakage from the battery is 105 uA. With the same conditions with VBUS at and above 5.67 V, the leakage from the battery is expected 13.7 uA. With the same conditions with VBUS below 3.35 V, the leakage from the battery is expected 9.7 uA. Please keep VBUS disconnected, above around 5.67 V, or below around 3.35 V to achieve desired IQ.

Hi Michael,
Datasheet Description VBus=0V-5V,Then the Datasheet description is wrong.
Hello,
We are working to investigate this. Can you please explain your use case and how this affects your solution?

Hi Michael,
The customer wants to confirm whether the test method is wrong or the specification is written incorrectly.
The customer thinks that too much leakage current will shorten recharge time.
Hello,
We are working on updating our datasheet for the next revision. As stated earlier, please keep VBUS disconnected, above around 5.8 V, or below around 3.2 V to achieve desired IQ.
