| Aug 21, 2023 at 9:27 | comment | added | Lundin | You can use a 74HC binary counter which toggles some BJT or shuts off its own enable pin once reaching a certain number. Not sure why you would want to do this with an analog circuit rather than a digital one? | |
| Aug 21, 2023 at 9:24 | comment | added | Ufuk Özgür | @ChengxianZhang Yes it should be work like that. I'm looking for the datasheets of the specified IC's right now. Is there any analog RC circuit alternative for that IC's? Thank you. | |
| Aug 21, 2023 at 9:18 | comment | added | Ufuk Özgür | @Andyaka T1 and T2 can be 2 or 3 seconds and the power supply rise time is not a problem with that range of time. And any voltage above 2.5V can be considered as threshold voltage. | |
| Aug 21, 2023 at 9:13 | comment | added | Ufuk Özgür | @Finbarr It's a requirement for this project. And i'm curious if it can be achieved with a analog circuit. | |
| Aug 21, 2023 at 9:07 | comment | converted from answer | Chengxian Zhang | Is it a power supply supervisor? Like CAT803 OR TPS3808? | |
| Aug 21, 2023 at 8:58 | comment | added | Andy aka | What if the 5 volts comes up slowly (as will happen with most power supplies)? What is the threshold at which the added circuit should begin to start its timer? You need to state T1 and T2 and allow a tolerance band. | |
