Hello, do you know how much current a GPIO input can handle? I'm using GPIO_AD_B1_02 and 8mA are flowing through that pin.
What is the maximum current an input can handle before damaging the pin?
The pin is on it's default values, if I understood right it is configured as input with 100k pulldown resistor by default
Thank you
Hi @jtrujillo,
In general, the maximum current for any RT1xxx GPIO pin should be limited to 25mA whether it is sourcing or sinking current. This is the safe limit for the technology to prevent reliability issues, like latent damage due to electromigration, and can be sustained for long durations if the pin needs to.
BR,
Edwin.
