DESCRIPTION
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 battery-
powered and power consumption sensitive applications.
The relay is constructed using a GaAIAs LED for actua-
tion control and an integrated monolithic die for the
switch output. The die, fabricated in a high-voltage
dielectrically isolated technology, comprised of a photo-
diode array, switch-control circuitry, and MOSFET
switches. In addition, the relay employs current-limiting
circuitry, enabling it to pass FCC 68.302 and other regu-
latory surge requirements when overvoltage protection is
provided. The relay can be configured for ac/dc or dc-
