Hi Andy Lui, We have done a series of testing in our board for evaluating the address switching issue, and our observation are listed below please check if these observations makes any sense 1.Initially we have connected the TSC2007 and its address configuring pins to a 3.3V rail with a rise time of around 1 ms, during this testing we observed the random switching of Address from 4B ( as per hardware configuration) to 48, also sometimes the I2C bus get hanged during the power ON time( during this time the SDA line is below low). So we modified the circuit to give provision to RESET the TSC2007 while the I2C Bus is down with a P Channel MOSFET, but surprisingly we couldn't able to reproduce the issue with this set up, so we have verified the switch on time of the MOSFET and is found to be around 250 uS. 2. So we changed the power rail to an another voltage rail with rise time of around 100 us and this time also we couldn't able to reproduce the issue, so we could you please confirm is there any dependency in rise of the voltage rail connecting to VCC and address configuring pins of TSC2007 . In the datasheet it is mentioned that the TSC2007 will automatically initiate a Power ON Reset once power is on, so could you please look in to this observation and confirm if there is any dependency with address switch??
