TLC59208F: Can we control N-FET directly with TLC59208F.

Hi Hoang,

TLC59208F is current sink device and I think it is OK to drive N-FET. Could you help share your schematic?

Hi Hardy Wu.

Thanks for your reply.

As bellow is my schematic.

-Pin Anode of Led will connect to VCC_LED

-Pin Cathode of Led will connect to WKx, RKx,GKx,BKx (x=0,1; ex WK0, WK1).

will it run normal when make PCB as bellow schematic?

Thanks and best regards.

Hi Hardy Wu.

If i also using P-FET as bellow schematic, is it correct?

About Led connection same above.

Thanks and best regards.

Hi Hardy Wu

i have confused with you advice,

You said that " When output channels open, voltage of gate would be pulled down. " that mean: Gate of P-FET should pulled down, but P-FET active when Gate pulled down so i think we must pulled up gate of P-FET.

could you give me some name of the P-FET it can saturation when TLC59208 active (in my design i had choose SI2307, is it ok)

Thanks you so much.

Hi Hoang,

Sorry that I may have some confusion words in the replay. What I said 'when output channels open' means turn-on the output channels. So the gate of P-FET would be pulled down and P-FET active, then turn on the LEDs.

Hi Hardy Wu

Thanks for your explain.

How about name of the P-FET it can saturation when TLC59208 active (in my design i had choose SI2307, is it ok?)

Thanks and best Regards.
