Final versioin of my soft-latching power switch.

Post by asgard »

Here is a schematic and breadboard photo for an improved soft-latch power switch circuit.
It uses a dual MOSFET with one P-channel and one N-channel device in the SO-8 device.
It should be able to switch up to 1A reasonably well.

I will have a short Vimeo video demonstration available Real Soon Now.

Vimeo just blows. Fuhgeddaboudet. I also dislike finding typos after I have posted. Urf.

hi, I really like your design, I wonder if you have a schematic that contains more detail for the capacitor and resister after JP-2, and also, what if I replace the AUIRF7343 with other Dual MOSFET?
