The MSC-LX1802 is the IC2 "Plug" for the MED427A-1 module.
The "Plug" chip has peak rectifier, level shifter, and switch.
This full wave peak rectifier converts the peak to peak AC input waveform to a DC level.
The charge builds up on both terminals of the storage capacitor to step up the DC level during a full wave input signal.
The charge dissipates via a resistor when the AC input signal stops.
The level shifter is a source follower
transistor with a resistive load.
The input connects to the peak rectifier output and th...
