| Driving a 5 v PNP with 3.3 volts pin | | 01/01/70 00:00 |
| Diagram ? | | 01/01/70 00:00 |
| Sketch.. | | 01/01/70 00:00 |

| Why push-pull? | | 01/01/70 00:00 |
| Thanks Rob | | 01/01/70 00:00 |
| Very much depending on chip | | 01/01/70 00:00 |
| Yeah, but ... | | 01/01/70 00:00 |
| Better always add a note for potentially dangerous methods | | 01/01/70 00:00 |
| Is that my responsability? | | 01/01/70 00:00 |
| Westermark | | 01/01/70 00:00 |
| Erik did exmplain | | 01/01/70 00:00 |
| Sorry Westermark.. | | 01/01/70 00:00 |
| KISS | | 01/01/70 00:00 |
| If it has not to be a PNP... | | 01/01/70 00:00 |
| Relay has to be driven.. | | 01/01/70 00:00 |
| since I would never do that ... | | 01/01/70 00:00 |
| Open drain pulled up to 5V.. | | 01/01/70 00:00 |
| did you read my post | | 01/01/70 00:00 |
| Deep waters | | 01/01/70 00:00 |
| OK, more | | 01/01/70 00:00 |
| I missed this post.. | | 01/01/70 00:00 |
| BC556 would turn on, wouldn't it? | | 01/01/70 00:00 |
| It wouldn't. Sorry. | | 01/01/70 00:00 |
| Have you considered a pMOSFET? | | 01/01/70 00:00 |
| Yep, I second that! Use a FET | | 01/01/70 00:00 |
| Have you considered that he must drive a 5V relay? | | 01/01/70 00:00 |
| Does that really matter? | | 01/01/70 00:00 |
| To what do you connect the source of this pMOSFET?? | | 01/01/70 00:00 |
| It's the switched drain current that does the work | | 01/01/70 00:00 |
| Of course, it does! But... | | 01/01/70 00:00 |
| One could also use a "switch" ... | | 01/01/70 00:00 |
Yes, that's safe! | | 01/01/70 00:00 |
