No. 7980 CSA – Certification 093751 FIMKO Approval APPLICATIONS General Telecom Switching – Telephone Line Interface – On/off Hook – Ring Relay – Break Switch – Ground Start Battery-powered Switch Applications Industrial Controls – Microprocessor Control of Solenoids, Lights, Motors, Heaters, etc. Programmable Controllers Instrumentation See Application Note 56 DESCRIPTION The LH1525 relay as SPST normally open switches (1 Form A) that can replace electromechanical relays in many applications. The relay require a minimal amount of LED drive current to operate, making it ideal for batterypowered and power consumption sensitive applications. The relay is constructed using a GaAIAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated technology, comprised of a photodiode array, switch-control circuitry, and MOSFET switches. In addition, the relay employs current-limiting circuitry, enabling it to pass FCC 68.302 and other regulatory su...
