I see an idle current of 1uA but nothing else to be concerned about (quick scan) https://datasheet.lcsc.com/szlcsc/1912111437_Gainsil-GS4157-CR_C280709.pdf Making a simple prototype can also shed light on that subject...? |

| obiwanjacobi:
I interpreted that as max current to sink or source...? More a load thingy..? |
| ELS122:
Well the ”VCC or ground” part makes me think it's power line current draw. Idk, gonna think this over more tomorrow! |
| ELS122:
but isn't 100ma a shit ton of current? it would mean that it like dissipated half a watt of heat. and I don't know much about surface mount packadges but that seems a whole lot for that smol ic. |
