Hi All,
I'm using circuit below
Q2=2n7000A; Q1=IRF9540N
C1=not installed; R1=R2=10k; Vin = 15V; gate Q2=0 or 5V
The circuit is used to switch on power with an Arduino. This (in principle) works fine.
After using te circuit for 10, times Q2 failed. Which can happen I suppose.
I've replaced it, and after some usage it is burned again....
Chances are there is something wrong here causing Q2 to fail, not sure what that is. Any help is appreciated.
The load used so far is only a led with a resistor, it will be used to power an H-bridge connected to a coil (+/- 1A).
Thanks,
I see there is a "p" missing in the title, but can't correct is apparently..
