BQ40Z80: Full Charge (FC) LED display

Patryk Szczesny

Part Number: BQ40Z80

Hi TI Team,

I have a question about the LED configuration.

When the "LED display during charging" is enabled, do the LED display behave like when triggered by the DISP button? Such as when set for mid-point config each set percentage of SoC will be displayed untill the charging process being completed?

Kind regards,

Patryk Szczesny.

Hello Patryk,

The blink midpoint will operate regardless of the LEDCHG configuration. When LEDCHG is enabled the most significant LED will blink during charging. It will continue to blink even after the charge current has stopped for the Chg Relax Time threshold value.

I would recommend evaluating on an EVM to verify if the operation is as expected for the application.

Sincerely,

Wyatt Keller
