DESCRIPTION
APPLICATIONS
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, 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 lightning surge testing as per ANSI/TIA-968-B and
other regulatory surge requirements when overvoltage
protection is provided. The relay can be configured for
AC/DC or DC-only operation.
