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 (I
the incremental resistance decreases, minimizing internal
power dissipation. Overload currents are clamped at I
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.

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.
