APPLICATIONS
DESCRIPTION
• PCMCIA type 2 cards
The LH1540 relay is an SPST normally open switch
(1 form A) in small-outline packages (SOP). It requires a
minimal amount of LED drive current to operate, making
them ideal for battery powered and power consumption
sensitive applications.
• Battery powered switch applications
• General telecom switching
• Telephone line interface
- On/off hook
The relays are constructed using a GaAlAs LED for
actuation control and an integrated monolithic die for the
switch output. The die, fabricated in a high-voltage
dielectrically isolated BCDMOS technology, is comprised of
a photodiode array, switch-control circuitry, and MOSFET
switches. In addition, the relays employ 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.

FUNCTIONAL DESCRIPTION
Figure 1 shows the switch characteristics of the relays. The
relay exhibits an on-resistance that is exceptionally linear
through the origin and up to the knee current (IK). Beyond IK,
the incremental resistance decreases, minimizing internal
power dissipation. Overload currents are clamped at ILMT by
the internal current-limit circuitry. The current-limiting
circuitry exhibits a negative temperature coefficient, thereby
reducing the current- limit value when relay temperature is
increased. An extended clamp condition, which increases
relay temperature, decreases the current-limit value,
resulting in a current fold back characteristic. When the
overload is removed, the relay resumes its normal
on-resistance characteristic.

Fig. 1 - Typical AC/DC on Characteristics
In a 1 form A relay, to turn the relay on, forward current is
applied to the LED. The amount of current applied
determines the amount of light produced for the photodiode
array. This photodiode array develops a drive voltage for the
MOSFET switch outputs. For high temperature or high-load
current operations, more LED current is required.
