The MID400S is an optically isolated AC line monitor with an 8-pin surface-mount package (lead bend). It interfaces AC line voltage to logic-level outputs using two back-to-back GaAs LEDs and a high-gain detector circuit. It operates with a 5 V supply and provides TTL-compatible open-collector output. The device offers 2,500 VAC RMS isolation and meets UL1577 and DIN EN/IEC 60747-5-5 standards, with a maximum working insulation voltage of 630 Vpeak. It supports externally adjustable AC sensing level and time delay via an auxiliary capacitor. Operating temperature ranges from -40°C to +85°C. The part is RoHS compliant.
