| Power pins on connector |
| (1/3) > >> |
| Epaperman:
If your power connector pins are rated for 1 amp but you need to load 1.5A.. can you use 2 contacts? Note.. contacts have a resistance.. |
| tszaboo:
What connector are you using? Is it hot-plug? |
| Neomys Sapiens:
If you can, use three. At least you would be safe against a single failure. But under design review, it might not pass everywhere. |
| Gregg:
I've seen numerous hot swappable power supplies that use multiple pins or edge card connectors in parallel to achieve the power requirements. As Neomys stated, use three instead of two; N+1 redundancy is always preferable to barely getting by. |
| Richard Crowley:
Yes, you can see that done in practically every computer on this planet. There are probably 100s of millions of examples of using parallel pins to increase current capacity. |
