What is the maximum current value from GPIO/PWM pin?

Hi everyone,

I am going to use GPIO pin as output/PWM output to drive N-MOSFET gate with logic level voltage input (e.g. International Rectifier IRLR2905Z or IRLR3705Z). I need to know what is the maximum current value of this pin to calculate the proper value of input gate resistor limited first current pulse while turning on the N-MOSFET thru gate capacity. I tried to found it in the UM10360 datasheet but with no result.

Best regards,

Jacob

Hello Jacob,

Please check the following datasheet of the LPC1769  

https://cache.nxp.com/docs/en/data-sheet/LPC1769_68_67_66_65_64_63.pdf 

In table 8. Static Characteristics you are going to found the value required.  

Best Regards ,

TIC
