Hi,

For the i.MX8QM, what is the max allowed current of the internal ESD protection diode

for a GPIO Type 1.8V IO single supply ball?

Thanks in advance.

Hi Ofer

unfortunately such parameter was not characterized and not described in datasheet.

One can consider 1 mA as safe as described in AN4731 Understanding Injection Current 

sect.3.2 Externally limiting injection current

Hi Ofer

 

>Have you received any additional information regarding the above?

not, sorry. This data is not characterized and not provided in datasheet.

Also there is no such data for other i.MX processors.

If you wish that such info was added to datasheet, suggest to apply to

local marketing office and provide solid reason for such additions.

Best regards
igor

Hi,

Thank you for the reference.

Since it is not listed in the datasheet, Is it possible to have the ESD diode specs from the team familiar in specific with the i.MX8QM internals?

Thank you for your support!
