The industrial AI edge gateway supports writing AI inference results to eMMC or SSD instantly upon power failure. The backup circuit requires a supercapacitor or large-capacity electrolytic capacitor (2200μF/50V) in parallel at the power input, and an ideal diode in series to prevent backflow. A TVS 5.0SMDJ33CA is also connected in parallel to absorb surges. When the main controller detects a power failure, it activates the backup power supply to complete the data writing. Actual testing shows that it provides a 50ms hold time after a power failure, backing up 1MB of inference data; the data remains intact after power is restored.
