Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

Description
The MID400 is an optically isolated AC line-to-logic inter-
face device. It is packaged in an 8-lead plastic DIP. The
AC line voltage is monitored by two back-to-back GaAs
LED diodes in series with an external resistor. A high
gain detector circuit senses the LED current and drives
the output gate to a logic low condition.
The MID400 has been designed solely for the use as an
AC line monitor. It is recommended for use in any AC-to-
DC control application where excellent optical iso- lation,
solid state reliability, TTL compatibility, small size, low
power, and low frequency operations are required.

$pplications,QIRUPDWLRQ
The input of the MID400 consists of two back-to-back
LED diodes which will accept and convert alternating
currents into light energy. An integrated photo diode-
detector amplifier forms the output network. Optical cou-
pling between input and output provides 2500 V$&
RMS
voltage isolation. A very high current transfer ratio
(defined as the ratio of the DC output current and the DC
input current) is achieved through the use of high gain
amplifier. The detector amplifier 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, RIN, in series with
theinput (as shown in ILJXUH) to limit the current to the
required value. The value of the resistor can be deter-
mined by the following equation:
Where,
VIN (RMS) is the input voltage.
VF is the forward voltage drop across the LED.
IIN (RMS) is the desired input current required to sustain a logic
“O” on the output.
