Part Number: BQ40Z80 Other Parts Discussed in Thread: BQSTUDIO Tool/software: I am a software engineer integrating our product externally with a BQ40Z80 over SMBUS / I2C. The battery component is still in development and so I am doing early integraion…
Hi Manas,
OverAgent712 said: For battery status, yes the gauge needs to display the SOC via LEDs when the button is pushed. What can be done to achieve this?
This can be achieved using the DISP pin functionality of the device. How to configure this can…
Hi Shubham,
Is it possible to share the full schematic so we can get a better idea? Just to confirm, the biggest concern is whether the 28V being applied to PACK at this time is going to damage the device?

Hi Manas,
Understood, the MCU on the bq40z80 EVM is 3.3V, so it can be used as a reference seen below:
SMBD1 and SMBC1 are from the bq40z80, where they are pulled up to 3.3V using 10kOhm resistors.

Hi Nick,
I think ESD can cause IC damage.
However, I encountered a NACK after sealing the BQ40Z80.
If I don't seal it and reprogram the srec, it can return to normal.
So I don't think it's due to ESD.
What do you think?
