TPD12S015A: 5V boost 5VOUT maximum current and short protection mode

Hi Cameron,

The 5-V power pin F1 can supply 55 mA of regulated current to the HDMI receiver.

The absolute max I_out is 100 mA when 55 mA is the typical value,.

So 55~100mA, the silicon may still function as designed; when > 100 mA, 5V cannot be maintained and will drop, and may trigger OCP.

There's no description on how the OCP works so I'm not clear. Generally a OCP performs a shutoff rather than current clamping/rail drop.

Hi Sam,

1. I don't see any public-released information about the OC mechanism. 

2. Based on the HDMI spec 2.2 if the cable pulls too much power it's a fault condition, and i believe you should see a disconnect

3. Test with your HW design to verify is suggested.
