I have made a board with a Due (Core) and 4 TPL7407L low side drivers to drive relays and LEDs in buttons on my project car.
I have got everyting programmed and working flawless, the only annoying problem I have now, is that all the things driver by the relays (wiper, washer pump, headlights, turn signals, horn etc.) and all the lights in the switches flash on for about 0,5 seconds when I turn on or off the ignition.
I have GND and battery 12v connected to the TPL7407 drivers, and the arduino is turned on and off by the ignition.
The TPL7407 drivers needs a high input to turn the outputs on.
Is there any way to stop the outputs from going high during startup and shutdown of the arduino?
