The light does not turn on after the power is powered on or does not turn on for 2 minutes. The replacement of the last batch of materials was found to be back to normal, please help to check the reason, thank you

There is no light shown in the schematic.

Please show an oscilloscope trace of the I²C access that would switch on the light, and of the corresponding P0x pin.

Hello,

If possible please provide the scope captures for I2C and P-pin as mentioned by Clemens. To confirm the device marked APE8 is presenting this issue while the other did not correct?

Regards,

Adam

User6350528,

Where did you buy the "PF575 1CKG4 CTRD" units from? This lot trace code is not showing up in our system as the device described.

Regards,

Tyler
