This pulse is a flat 3,3V signal, no power up glitches or something. It turns on both FETs and can create problems.

Looks like your PA inputs can source as much as uA of current. Welcome to the club.

The only disadvantage of using the pull-down resistor to overdrive the pull-up is that you have to allow for the maximum pull-up current possible over temperature and process. Simple cheap and compact.

My problem is that I get a high impulse at power on of about 25ms, which is enough for the relais to switch.

I ended up using a hand full of Transistors to cover these issues properly. Create free account Forgot password? Protecting the IoT with Invisible Keys.

It seems that At91sa7x need external pulldown to compensate them I was going to ask what your drive configuration was. Sign in Sign in Remember me Forgot username or password?

datashedt I know that the ULN is designed for 5V pegel, but 3,3V gives enough current to safely drive my relais. A very minor nit.

So a 1 kohm pull-down should do the trick. Then the default state is for at91sa7mx256 transistor to be on and the internal pullup does not hurt.

Therefor use extra transistors — they do inverting for you for proper PowerUp. Arduino Robotics Lonnie Honeycutt. Introduction to At91sam7x Mike Silva. Medias this blog was made to help people to easily download or read PDF files.
