Pin Function Grouping for Datasheet

A

adrian95

Looking at the datasheet of this component, can you group together pins by their functions? for example for Power, BAT, VSS etc
Also can you place them into their respective sections based on their functions
NOTE: If you group them, can you not add the same pin if you already added them in a group? You should know which pin function is common for its function

I’ll extract the BQ41Z50 pin table from the datasheet, compare it to the current 33 pads, then update each pin’s functional group/section without duplicating any pin across groups.

flux

Done — I grouped all 33 BQ41Z50RSNR pins by datasheet function and placed each pin into one functional section only, with no duplicate pin assignments.
I also updated the pin descriptions and normalized the electrical pin types where possible: SMBus/GPIO/FUSE as bi-directional, analog sense pins as inputs, VSS/EP as ground, VCC/BAT as power inputs, and REG18/REG135 as power outputs.
