Title: Help with unknown smd IC
Post by: error21 on July 28, 2019, 04:36:01 pm

Hi
   Could somebody please help me with the following IC? They are from 2 different products and I THINK they are used to measure the input current.

   I did look on google but could not find anything

   What I did measure is that PIN2 is GND and PIN5 is +5V and between 3 and 4 there is a 100K resistor
Thanks
