    PSoC 4200L drive current on GPIO pins





      I am using a CY8C4248LTI-L485 chip to drive an LC circuit to generate a magnetic field. I would like to know the max current I can pull from on these GPIO pins, as there's a lot of confusion in the info I am receiving.


      On the datasheet, the absolute max current is 25mA, and in the PSoC creator software, the source current on the pin configuration window is only 4mA. However, I have measured more than 55mA on a single pin.


      Please let me know what is the actual current on rating on these, and if I need to short 4 GPIO pins together to drive higher currents.
