4.8 Thermal Management
COMX-P4080-2G-ENP2 provides a thermal management strategy. This includes CPU junction
temperature monitoring.The following diagram shows thermal management strategy:
A thermal diode is integrated in P40x0, which connects to a thermal sensor ADT7411. The CPU
can get the junction temperature via I2C.
When the junction temperature goes up to105
o
C, ADT7411 drives INT# to low, indicates an
interrupt to CPU. A red LED D17 can show the interrupt status.
