Description
The LH1550 is robust, ideal for telecom and ground
fault applications. It is a SPST normally open switch
(1 Form A) that replaces electromechanical relays in
many applications. It is similar to the LH1540, but has
a characteristically higher On resistance. It is con-
structed using a GaAIAs LED for actuation control
and an integrated monolithic die for the switch output.
The die, fabricated in a high-voltage dielectrically iso-
lated technology, is comprised of a photodiode array,
switch control circuitry and MOSFET switches. In
addition, it employs current-limiting circuitry which
meets FCC 68.302 and other regulatory voltage
surge requirements when overvoltage protection is
provided.
