Documentation vs. Practical Doubts

[Alvazz]

Hi, Very nice work, thank you for your hard work. But after I saw this, I got a little confused, it says LM5107, but the actual schematic is 2ED2304S06F, am I mistaken?

Version 7
---------
|--- Add Schottky between phase and gnd at HS pin of LM5107
|--- Add 5R6 in phase line to HS pin of LM5107
|--- Change high side bypass cap to 10u/25V
|--- Add 14V TVS diode parallel to high side bypass cap
|--- Add one 12V TVS diode to 12V near driver
|--- move gate tracks and back from side by side to on top of each other

Oh, dont Update the documentation. Schematic is correct. The ED is a really nice driver

Thanks!

One more new doubt, what is the use of SN74LVC1G66DBVR device in this schematic? Thank you for your guidance!

[CTSchorsch]

U9 is a analog switch. the vesc-firmware supports to switch some additional filtering for current measurement and phase voltage measurement. in this picture the additional cap C41 is connected to the filter R33/C47

[Alvazz]

Thanks! What are the benefits of doing this?

[CTSchorsch]

on high motor current there is more ripple on the signals and you can add more filtering. But there are many vesc-versions without this additional filter option. i'm thinking about too remove it too on a next version

Thank you for your guidance, mainly to play a filtering role
