Okay, so the min gate threshold voltage is when the resistance in the mosfet will become low enough to start letting some current through but as the voltage becomes higher, the resistance in the mosfet will keep dropping until it reaches the max gate threshold voltage where the resistance in the...
Im using it to power LEDs than run at very low current, about 20mA and the max voltage will be only 5.5V. It is not necessary for the MOSFET to switch instantly but would be better if it did. I am making a small crank light and I want the capacitors to go straight to the LEDs until the voltage...
I need a MOSFET transistor that will turn off anywhere between 2.5-2.7V and stay on when above that voltage, looking through the datasheets of these transistors, what spec should I be looking for?
Here are some I've found that I think may work...
I'm working on a small crank-able light using a DC motor,capacitors, and LEDs with a joule thief to drain the capacitors completely when the voltage in them drops too low for the LEDs. However I want the power from the capacitors to be able to go directly to the LEDs before the capacitors drop...
