Hello:
We just completed a second production batch of our product using the ICS-43434 after a previous successful run. On this batch, the ICS-43434 overheats at power up and dies quickly. Is there a known batch issue? The lot code is 434-VQG6J
There is a countpart: RCOSC, but I can’t find explanation of WUOSC in datasheet. Could any expert help me？ Thanks.

I’m having trouble using the ICU 20201 product; I’ve wired it to the designated SPI pins on my Arduino due, but despite uploading the sketch to the Arduino from the presence example available for Arduino, I can’t successfully connect to the sensor. Has anyone encountered similar problems and/or know a solution?
