I am working on a system utilizing the PN7462AUHN to read NFC tags. I noticed that at certain temperature band within the operational temperature range the system fails to read the NFC tag consistently. Once the chip rises above the temperature band it can read without issue. Has anyone seen this behavior with this chip before?
I noticed there is a similar issue in the support queue, the case subject is Communication and Thermal issues associated with PN7462AUHN. is this yours? I will respond in that case. Thanks for feedback.
PN7462 has been tested at full temperature range. Not found this issue as you mentioned. I would suggest you check your design, layout, power design , and antenna design.
