DESCRIPTION
The LH1526 relay are two SPST normally open switches
that can replace electromechanical relays in many
applications. The relays 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 actuation control
and an integrated monolithic die for the switch output.
The die is, 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.
