Description
The LH1525 relay are SPST normally open switches
(1 Form A) that can replace electromechanical relays
in many applications. The relay requires 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 actuation control and an integrated
monolithic die for the switch output. The die, fabri-
cated in a high-voltage dielectrically isolated technol-
ogy, 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 surge requirements
when overvoltage protection is provided. The relay
can be configured for ac/dc or dc-only operation.
