Followed the first bit ok.. but the last paragraph went somewhat over my head I must confess.
There will be multiple on off events for sure, if there's a problem it could be catastrophic given the load I'm considering.
The avalanche is where the mech switch becomes redundant and current...
I'll sure give it a go, thanks FvM.
I was really hoping the P to N change was as simple as that but I had no clue if the resistor or capacitors value would need to change, following a diagram is about where my skill ends unfortunately.
I'll not hold it against anyone if they drew it out for me ;)
Can I ask if someone could show me this circuit diagram with N channel mosfet instead of P please. I'm not skilled enough to design it myself :/
Ive had a thought that If I do not use the monitoring device I was planning I could use an N channel switch and monitor the thermal output externally...
Thanks for your help! Owe you one :)
(I'd also like to apologise for the warning I received, I couldn't see another way to attach an image using mobile version. Sorry.)
I dont really know what your end result is, but if you can dissipate energy as heat then Nickle coils gain good resistance as they get warmer. I might have the resistance temp coefficient somewhere if that's a solution you can use?
The battery spec on the diagram is outdated, sorry, my bad. It'll be powered by a 7.8v 2S lipo silicone-graphene 46wh battery first off, allowing provision for a more powerful cell later on. The circuit is only live for a few seconds at a time every few seconds, so the overall battery life will...
Hi there. I intend to use a 7.8v 46wh lipo battery to power a 0.12ohm heating element, I can only use p channel mosfets as the switch because of a digital read out I plan to add will act to complete an N channel circuit. I've been given a circuit to work to but to be honest I know very little...
