Hello,

We have a supply voltage that it is take too much time to achieve Vdd.
Is It  not possible modify the valid threshold voltage to put it higher?
Or How can we provoke internally a reset after the Vdd has achieve its value?

I am thinking about to use this MCP111/112 chip but it makes an expensive board which I didn't expect.


Thanks in advance.

You could either use an R-C netwrok to hold the reset line low for longer, or use a DS1818 (or similar).

Regards,
Mike
