Quick question on PIC driving FET 2N6796

Hi to all,

Just wondered if anyone knows if I can drive a 2N6796 FET directly from the PWM output of a PIC?

I wondered because I only have experience in driving normal transistors where the gain is important, and have never used a FET as a driver before.

The FET will be switching 20v at 350mA (a string of 1w leds) and I can't figure out the FET datasheet.

Is there a relationship between gate current/voltage with gain on FETs or is it just on or off?

Thanks for looking..........Al

Yes, should be fine in this application.

Thanks mate. I'll get out the breadboard now then!

Update

Hi Pete,

Just to let you know that the FET does indeed work ok from PIC PWM, I'm up and running now.

Thanks for the quick confirmation mate.
