DP83822H: Maximum current on LED pins 17, 24

KKF

Part Number: DP83822H

Hi,

I have a question to your part DP83822H:

I cannot find any information about the maximum allowed pin current on LED Pins (Pin 17, 24).The output voltage levels are characterized at 4mA Pin current, but there is no max. value for allowed pin current given.

Could you please provide these information (I_OH and I_OL)?

Thanks & BR,
KF

Hi KF,

One way to look at the pin driving capability is from the IBIS model.

Here is the link to DP83822 IBIS: www.ti.com/.../snlm205

Hi Hung Ngyen,
My customer is struggling extracting the relevant information from the IBIS model. Do you have a chance to provide this information? I can also reach out to you per email if it helps.

Hi KF,

From the IBIS model, one can view the I-V curve which provides the relationship between pin voltage and current.
