| Mar 4, 2018 at 20:50 | comment | added | bigjosh | @Unknown123 You are absolutely right! Thank you for the correction. I've updated the value of R2 and a couple of the calculations to reflect this. Thanks again! | |

| Mar 4, 2018 at 15:55 | comment | added | Unknown123 | Are you really sure about this? What I've just read is that \$VIH2\$ is 0.9*VCC Volt not 0.9 Volt | |
| Aug 13, 2017 at 3:10 | comment | added | bigjosh | @ThatAintWorking I think a zener would work fine, but is over kill. As long as the RESET pin is above 0.9 volts, the chip will not reset and as long as you can see the voltage drop (whatever it is) on the analog input, then everything is good. | |
| Aug 12, 2017 at 21:56 | comment | added | ThatAintWorking | Is this better than using a 3v3 zener diode instead of R2? With the 1k resistor, it gives the reset pin 3V by my voltmeter. | |
| Oct 14, 2015 at 9:23 | comment | added | cocco | i knew there was a simpler way!.... thank you for your precise answer... i tested it and it works perfect! btw i'm using 10k resistors.... | |
