BQ40Z60: Removing unused parts from the design

Genius 16079 points
Part Number: BQ40Z60
Other Parts Discussed in Thread: BQ40Z50

Hi Experts,

Seeking your assistance on this query from Cx:

We decided to use bq40z60 IC in one of our products for 2S Li-Ion battery. Could we connect VC3 and VC4 to VC2 directly? Additionally, in our design, we won't need external thermistors and LEDs. Could we keep them float or connect GND? I read datasheet, technical reference and EVM module sheet of bq40z60 but I didn't find any information about not using.

Documents of an IC from same family, bq40z50, I saw a note that "Unused LEDCNTL pins can remain open or they can be connected to VSS." But for bq40z60 I didn't saw any guidance.

Regards,
Archie A.
