DESCRIPTION

Description
The LH1526 relay is 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 batterypowered 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, 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 FCC 68.302 and other regulatory surge requirements when overvoltage protection
is provided. The relay can be configured for ac/dc or
dc-only operation.

Applications
Input Control
The LH1526 low turn-on current SSR has highly sensitive photodetection circuits that will detect even the most minute currents
flowing through the LED. Leakage current must be considered
when designing a circuit to turn on and off these relays.
Figure 19 shows a typical logic circuit for providing LED drive
current. R1 is the input resistor that limits the amount of current flowing through the LED. For 5.0 V operation, a 2700 Ω
resistor will limit the drive current to about 1.4 mA. Where
high-speed actuation is desirable, use a lower value resistor
for R1. An additional RC peaking circuit is not required with
the LH1526 relay.
R2 is an optional pull-up resistor which pulls the logic level
high ouput (VOH) up toward the VS potential. The pull-up resistance is set at a high value to minimize the overall current
drawn from the VS. The primary purpose of this resistor is to
keep the differential voltage across the LED below its turn-on
threshold. LED dropout voltage is graphed vs. temperature in
the Typical Performance Characteristics section. When the
logic gate is high, leakage current will flow through R2. R2 will
draw up to 8 mA before developing a voltage potential which
might possibly turn on the LED.
Many applications will operate satisfactorily without a pull-up
resistor. In the logic circuit in Figure 1 the only path for current
to flow is back into the logic gate. Logic leakage is usually negligible. Each application should be evaluated, however, over
the full operating temperature range to make sure that leakage
current through the input control LED is kept to a value less
than the minimum LED forward current for switch turn-off
specification.
