BQ41Z50: Number of leds supported

Martin Bařinka

Part Number: BQ41Z50

Tool/software:

in datasheel (slusfb5) is stated, that BQ41z50 support up to 3 LED display.

But reference manual (sluucp8) chapter 8.2, there is mention of 5-LED display and five registers to set thresholds.

I don't see a way to connect five LEDs to BQ.

What is the limit of LEDs connected?

Hi Martin,

I believe it is only three, in the past we used charlieplexing to allow for a 5-LED display, however this has been removed from this device.

Hi, thanks for reply.

This is not good news for me. Anyway is there a plan to fix documentation? I think i found more things that are not completely described.
