Hi Sir,
We use your company's NXQ1TXH5 produced in week45 of 2002 and stop charging when the current slowly rises above 1A.

Your company's answer is as follows:

---------------------------------------------------------------------------------------------------------------

Customer could start with those steps to narrow down what is causing the fault:

(Try each one individually, (after each go back to configuration before changes.)

Replace resistor connected to CNF1 pin with short, 0 Ohm.

This will turn off SPR static power reduction and SPL smart power limiting.

Replace resistor connected to CNF3 pin with short, 0 Ohm.

This will turn off FOD foreign object detection.Wireless Connectivity

Short NTC pin to ground.

This will turn off external NTC sensing and 85 deg C power reduction threshold.

----------------------------------------------------------------------------------------------------------------
However, these tests are not improved.
I short NTC3 pin to ground and it can charge.
What is the correct solution?
