Hi Bogey,

I found the datasheet. I will send you a friend request notification because I do not want to place my email on the forum.

Hi Bogey,

The closest devices come close to G781 are LM86 and LM89. They are P2P replacement for G781. I reviewed both device's register map. The LMxx devices doesn't have the register 0x22. Most of the default limit value doesn't match G781.

Hope this helps. Let me know if you have further questions.
