Description
The LH1525 relay is an SPST normally open switch (1
Form A ) in small-outline package (SOP 8 pin). Relay
requires a minimal amount of LED drive current to
operate, making relay ideal for battery powered and
power consumption sensitive applications.
The relay is constructed using a GaAlAs LED for actu-
ation control and an integrated monolithic die for the
switch output. The die, fabricated in a high-voltage
dielectrically isolated BCDMOS technology, is com-
prised 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.
