BQ25180: Ship mode current details

Part Number: BQ25180
Other Parts Discussed in Thread: BQ24296

Hello Experts,

We are using BQ25180YBGR. I want to know current consumption in Ship mode and idle condition, When I press pushbutton(TS/MR) for 10 sec, current shown 10-30uA that means IC goes to ship mode correct? 

Also we are planning to change BQ25180 to BQ24296MRGER, So Could you please provide current consumption in Ship mode and Idle condition for BQ24296MRGER?  

Thanks

    Hi,

    the quiescent currents are:

    BQ25180

    - Shut down: 15 nA

    - Active BAT mode: 3 uA

    BQ24296

    - idle: 32 uA

    - BATFET disabled: 16 uA

    Best Regards,

    Hello,

    Thanks for the values.

    When I press pushbutton(TS/MR) for 10 sec, current shown 10-30uA that means IC goes to ship mode correct?

    BQ25180 - Active BAT mode: 3 uA means idle condition? what is ship mode current?

    Hi,

    Active BAT mode is used to describe the mode during which the device is operating via Battery power in order to maintain the SYS load. You could describe this as idle condition as this will be the condition which the application will spend most of the time that it is in active mode (not in a low power state).

    The device in shipmode will consume a typical current of about 3.2 uA, but in shutdown mode it will consume 15 nA.

    Can you clarify, 10-30 uA from battery? This seems a bit higher than expected for shipmode. During this mode can you execute I2C transactions and what is the SYS voltage?

    Hi,

    Yes, 10-30 uA from battery.

    How can we verify Shipmode is enable or not? 

    SYS voltage is 0 volt.

    We also observe 10-30 uA is not constant, its some time goes to 100uA.

    Hi Hitesh,

    Apologies for the delay.

    The fluctuations in charge current are not expected behavior, and 100 uA is far outside the expected quiescent current for this device. Is there any load that is directly connected to the battery? Or is it possible this IC has sustained damage?

    If you attempt to communicate with the device via I2C, is the device acknowledging the transaction?

    Best Regards,
