Part Number: BQ35100

What is the current consumption of BQ35100 in ACC mode?

In spec, it is 130uA.

But we test bq35100EVM in ACC mode, the consumption is about 160uA.

What is the normal current range of ACC mode? Is 160uA normal?

Hello User,

It is more of a typ range for the 130 uA number.

Yes, 130uA is a typ value.

We measured the consumption of BQ35100 on our products and BQ35100EVM. It is 160uA/3.7V(164.4uA/3.6V). Higher than 130uA.

We have to write a spec for our power test and explain to our customer about 164uA consumption.

Please help to confirm if 164uA is normal. Thank you!

Hello User,

I cannot confirm. Please just let customer know the typ spec in the DS. This part runs FW, the max spec becomes very dynamic.

Hi,

Thank you for your reply!

I can't find the accuracy of BQ35100 in SPEC.

What is the accuracy of BQ35100 when measuring current and charge accumulation? What is the accuracy of BQ35100 when current is higher than 10mA and lower than 10mA?

Hi,

For our product is powered by non-rechargeable battery. The power consumption is very vertical.

Please help to confirm the power consumption of BQ35100 in ACC mode. The max spec becomes very dynamic, can it high to 200uA or 300uA or more?

Is 130uA a measured value or a calculated value?

It runs FW. So 130uA is measured in which version of FW?

Hello User,

It is hard to discuss specifications for items with no max spec on the datasheet. My recommendation is that you measure this out in your system under the conditions the system has to handle.

That will be the best system use case measurement you will be able to get from this device.
