SC18IM700 IC is driving an LM73 temperature IC via I2C bus.
The SC18IM700 appears to reset the IC/GPIO at 40-50C.
Is there any solutions to this
The operating temperature range of the SC18IM700 IC is from -40C up to +85C (ambient temperature), there should not be any problem using it at 40 or 50C.
Is this issue happening in all your boards? Did you tried to do a swap test (replace a “not-working“ device with a “working good” device)?
