Built-in shutdown logic protects the card from damage by removing power to the FPGA when either electrical or thermal limits (given in the following table) reach or exceed their respective card shutdown thresholds. VCCINT current and temperature are monitored by the card regulator while FPGA temperature is monitored by the satellite controller (SC). Power to the card SC remains on during card shutdown. Card shutdown protection logic is always enabled and cannot be disabled.
The following table lists the card shutdown power and thermal thresholds.
