If it enable the OTP setting in the Configuration Utility, some setting items will be showed. Please tell me the meaning of these.

Or, if it is mentioned in the documentation, please tell me where it is.

Mallika-san,

Thank you for your reply.

The Cutoff value is 5000. Is this unit the temperature in degrees Celsius? What is the reason for the extremely high value?

Hi,

It is the GPIO voltage (in mV) corresponding to the temperature at which OTP cutoff is to be performed.

Mallika-san,

My understanding is that It is the voltage threshold of the GPIO to which the thermistor is connected. Is it correct?
And, where is it discribed that the unit is mV?

Thanks,

Hi Tetsuo,

It is the cut-off voltage across thermistor. CCG3PA monitors for this cutoff voltage and when the voltage across thermistor drops below the cut-off range, OTP fault condition is triggered.

Mallika-san,

I understand the explanation of the cutoff voltage.

Where is it described that the unit is "mV"?

Hi,

I checked internally about the parameters and confirmed the unit.

Is there a way for users to check this in the documentation or tool help?

Hello Tetsuo,

All the necessary information is already provided in the EZ PD Configuration utility guide and the KBA which I pointed to in one of my previous response. In case of any additional queries, kindly let me know. I'll help in clarifying your doubt.

Regards,

Mallika
