BQ40Z80: LED connection

KIM

Part Number: BQ40Z80

Hi,

We would like to use 3 LEDs to displaying SOC instead of 6 LEDs (as in the data sheet).

Can you advise the physical 3 LEDs connection to the BQ40Z80 and the relevant setting to display SOC when button is pressed?

Thanks!

Hello Kim,

I would recommend reviewing the EVM LED configuration, if you need only 3 LEDs, do not populate the LEDs that you do not want the SOC displayed.

Hello Kim,

It depends on what LEDs you want to light up depending on the SOC.

The configuration you show will show 0-50% SOC.

If you want to display the full spectrum you would need to select different LEDs:

Like D7, D11 and D10 for example.

You can also keep your configuration and change the Chg Thresh 1,2,3 values to match your application.

Sincerely,

Wyatt Keller
