MID400SV

AC Line Monitor Logic-Out Device MID400 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. www.onsemi.com PDIP8 6.6x3.81, 2.54P CASE 646BW 8 1 PDIP8 9.655x6.6, 2.54P CASE 646CQ 8 1 Features • Direct Operation from any Line Voltage with the Use of an External • • • • Resistor Externally Adjustable Time Delay Externally Adjustable AC Voltage Sensing Level Logic Level Compatibility Safety and Regulatory Approvals: ♦ UL1577, 2,500 VACRMS for 1 Minute ♦ DIN−EN/IEC60747−5−5, 630 V Peak Working Insulation Voltage Applications • Monitoring of the AC/DC “Line−down” Condition • “Closed−loop” Interface between Electromechanical Elements such • as Solenoids, Relay Contacts, Small Motors, and Microprocessors Time Delay Isolation Switch PDIP8 GW CASE 709AC 8 1 MARKING DIAGRAM ON MID400 VXXYYT1 MID400 = Specific Device Code V = DIN EN/IEC60747−5−5 Option (only appears on component ordered with this option) XX = Two−Digit Year Code, e.g., “06” YY = Digit Work Week, Ranging from “01” to “53” T1 = Assembly Package Code FUNCTIONAL SCHEMATIC 1 8 V CC N/C 2 7 AUX 3 N/C 4 6 VO 5 GND ORDERING INFORMATION See detailed ordering and shipping information on page 8 of this data sheet. © Semiconductor Components Industries, LLC, 2005 April, 2021 − Rev. 2 1 Publication Order Number: MID400/D MID400 SAFETY AND INSULATION RATINGS (As per DIN EN/IEC 60747−5−5, this optocoupler is suitable for “safe electrical insulation” only within the safety limit data.
