PROBLEM TO BE SOLVED: To provide the hot-line insertion and extraction adaptive type electronic circuit package which can securely load a nonvolatile memory of an object device to be protected even if a rise of a source voltage applied at the time of hot-line insertion or extraction is unstable. SOLUTION: At the time of the hot-line insertion or extraction of the electronic circuit package 1 into or from a device main body, a power source monitor device 3 mounted on the electronic circuit package 1 monitors the transient variation state of the applied voltage, and outputs a load start command to the object device 2 to be protected which is mounted on the electronic circuit package 1 after the variation state becomes stable; and a load signal is outputted from a nonvolatile memory 2a of the device 2 to be protected to a nonvolatile memory 2b and after the loading of the nonvolatile memory 2b is completed, the power source monitor device 3 outputs a reset signal for resetting the whole electronic circuit package 1. |
