Description/Applications
The input of the MID400 consists of two back-to-back
LED diodes which will accept and convert alternating
currents into light energy. An integrated photo diode-
detector ampli?er forms the output network. Optical cou-
pling between input and output provides 2500 VRMS
voltage isolation. A very high current transfer ratio
(de?ned as the ratio of the DC output current and the DC
input current) is achieved through the use of high gain
ampli?er. The detector ampli?er circuitry operates from a
5V DC supply and drives an open collector transistor
output. The switching times are intentionally designed to
be slow in order to enable the MID400, when used as an
AC line monitor, to respond only to changes in input volt-
age exceeding many milliseconds. The short period of
time during zero-crossing which occurs once every half
cycle of the power line is completely ignored. To operate
the MID400, always add a resistor, R IN , in series with the

VOLTAGES
V I (ON) RMS On-State RMS Input Voltage
The RMS voltage at an input terminal for a
speci?ed input current with output condi-
tions applied that according to the product
speci?cation will cause the output switch-
ing element to be sustained in the on-state
within one full cycle.
V I (OFF) RMS Off-State RMS Input Voltage
The RMS voltage at an input terminal for a
speci?ed input current with output condi-
tions applied that according to the product
speci?cation will cause the output switch-
ing element to be sustained in the off-state
within one full cycle.
R IN = ---------------------- F -
input (as shown in test circuit 1) to limit the current to the
required value. The value of the resistor can be deter-
mined by the following equation:
V IN – V
I IN
Where,
V IN (RMS) is the input voltage.
V F is the forward voltage drop across the LED.
I IN (RMS) is the desired input current required to sustain a logic
“O” on the output.
