All I'm saying is you can use a MOSFET driver to eliminate the NPN and some resistors.

Or...possibly eliminate both the NPN and the MOSFET using the driver as long as you don't exceed the wattage rating of the driver.

The PDIP will probably do the job, but you could always use the TO220.

Choose the TC4420 or TC4429 depending on the MCU logic.

 

Sure looks like you can use the G input for PWM it's simply connected to AND gates that are on the NMOS gates.

 

Oh, can i use it for that, ?
PWM direct to this point ?

Datasheet says it's an output enable. That's what I would expect it to do.
(Don't confuse G with GND as you have them all labelled "G")

 

Why do you need a MOSFET? Why aren't you using the G input to the TPIC for the dimmer?

I was going to say that too.
Just feed the PWM signal to the "G" pin, without the transistor or FET installed, and it looks like that should work ok, if I read the data sheet correctly (just skimmed through it).

 

My problem is I don't read every data sheet, I simply address the problem as presented, I should probably change that practice.

Me too
I have not come across this part before. I just went looking for an enable pin and it seems to have one that would fix the problem..

 

I have to admit I've used it before - it works as a Nixie tube driver.
It's pretty much a 74HC595 with high voltage outputs.
