Hello Jonny,
I referenced the thread you provided and followed the mentioned steps as below.
1. Write CC_GAIN Address to the MAC Address
W 0xAA 0x3E 0x06 0x40
2. Write the new value for CC_GAIN to address 0x40
W 0xAA 0x40 0x3FEB020C
3. Calculate the …
Part Number: BQ27Z561 Hello Jose Couso ,
Sorry for replying late.
Thank you for you explanation in the BQ27Z561: Fuel Gauge Reading is not Proper after completing the learning cycle thread.
To confirm, we have enabled the IT Gauging Configuration bit [SMOOTH…

Hi,
We use the BQ27z61-R2 in our product.
During our production, we will flash the golden FW to the gauge chip on the PCBA(outer power supply) first, and then connect…
Hello Uri,
There is not any more tweaking that can be done outside of what you have already done to try and decrease the gauge iq in these different power modes. The device datasheet lists the expected average device iq in the different power modes. These…

We are using BQ27z561 fuel gauge IC and BQ25601 Charger IC in our custom board.
We have performed the learning cycle procedure. After successfully completing learning…
Hello Shivani,
I have answered your questions below:
Yes you can choose a charge rate other than C/2, this is just the recommended value. The charge rate will affect the speed of the learning cycle, but will not have an impact on the learning cycle performance…
