I am trying to use a IRF7832 MOSFET {datasheet here} to control a short LED strip.
I have connected the LED strip between 12 V and drain and 0V to gate and source. The LED strip has 6 strings of 3 LEDs. As I understand pin 5-8 is drain, pin 1-3 is source and pin 4 is gate so I have pin 1-4 to 0V and 5-8 to the LEDs.
I expect this to turn off the LEDs but they are turned on very dim and I measure about 4.5 V between drain and source.
If I connect gate to 5V the LEDs turn on and I measure 2.5 mV across drain and source.
I have tried 2 different IRF7832's.
What am I doing wrong?
