4.7 Thermal Management
The COMX-P40x0 ENP2 module provides a thermal management strategy. This includes CPU
junction temperature monitoring as shown in the following figure:
A thermal diode is integrated in the P40x0, which connects to a thermal sensor ADT7411. The
CPU can get the junction temperature via I2C.
When the junction temperature reaches105
o
C, the ADT7411 drives INT# low, to indicate an
interrupt to the CPU. The red LED D17 shows the interrupt status.
