| Jul 14, 2016 at 2:03 | comment | added | akhmed | I see -- this is an interesting idea. CircuitLab does not seem to like it though: it looks like any voltage on resetbar no matter how small is simulated as high digital signal - I guess they want me to use a digital IC here. | |
| Jul 13, 2016 at 22:14 | comment | added | jbord39 | It's worth a try; according to the datasheet the timer will start once resetbar=0.7V or more | |
| Jul 13, 2016 at 21:40 | comment | added | akhmed | @jbord39 wouldn't it require adding a digital IC? Or are you suggesting that reset would play well with the gradually increasing voltage from RC network directly? | |
| Jul 13, 2016 at 15:08 | comment | added | jbord39 | I would look into using the resetbar signal to create the initial delay. As an example, use an RC network to delay the pullup of the resetbar signal after powerup (by ~15s). | |
