The power management circuit 1 is electrically connected. The power supply end of the power management circuit 1 is coupled to the power connection end of the power input port 2. The power input port 2 supplies power to the DDR3 controller 3. The analog-to-digital converter 7 is coupled between the microcontroller 6 and the trigger circuit 8, and it is used to convert the control instruction from a digital electrical signal to an analog electrical signal.

[0037] AsFigure 2 As shown, the current detection circuit 4 includes a differential amplifier circuit.
