of the Arria10 FPGA rises, the MAX10 will increase the fan speed to decrease the
temperature of the FPGA.
In order to avoid the failure of the fan on the FPGA and stop the rotation and cause the
FPGA temperature to rise rapidly. When the FPGA temperature reaches 95 degrees
(The setting threshold value), the MAX10 will cut off the power supply to the Arria10
FPGA to avoid damage caused by excessive FPGA temperature.

Power Monitor
The TR10a-LPQ has implemented a power monitor chip to monitor the board input
power voltage and current.
shows the connection between the power
monitor chip and the Arria 10 GX FPGA. The power monitor chip monitors both shunt
voltage drops and board input power voltage allows user to monitor the total board
power consumption. Programmable calibration value, conversion times, and averaging,
combined with an internal multiplier, enable direct readouts of current in amperes and
power in watts.
