DESCRIPTION

The MID400 is an optically isolated AC line-to-logic interface 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 isolation, solid state reliability, TTL compatibility, small size, low power, and low frequency operations are required.

FEATURES

Direct operation from any line voltage with the use of an external resistor.
Externally adjustable time delay
Externally adjustable AC voltage sensing level
High voltage isolation between input and output
Compact plastic DIP package
Logic level compatibility
UL recognized (File #E90700)
VDE recognized (ﬁle #102915), – add option V (e.g., MID400V)

APPLICATIONS

Monitoring of the AC/DC “line-down” condition
“Closed-loop” interface between electromechanical elements such as solenoids, relay contacts, small motors, and microprocessors

© 2003 Fairchild Semiconductor Corporation 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 coupling between input and output provides 2500 VRMS voltage isolation. A very high current transfer ratio (deﬁned as the ratio of the DC output current and the DC input cur- rent) is achieved through the use of high gain ampliﬁer. The detector ampliﬁer circuitry operates from a 5 V 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 voltage 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 input (as shown in test circuit 1) to limit the current to the required value. The value of the resistor can be determined by the following equation: 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. DESIGNATION PIN # FUNCTION V IN1 , V IN2 1,3 Input terminals V CC 8 Supply voltage, output circuit.
