APPLICATIONS
INPUT CONTROL
The LH1525 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 23 shows a typical logic circuit for providing LED
drive current. R
1
is the input resistor that limits the amount
of current flowing through the LED. For 5 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 R
1
. An additional RC peaking circuit is not
required with the LH1525 relay.
R
2
is an optional pull-up resistor which pulls the logic level
high output (V
OH
) 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 R
2
. R
2
will draw up to 8 mA before developing a
voltage potential which may possibly turn on the LED.
Each application should be evaluated, 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.
