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
of current flowing through the LED. For 5 V operation, a
2700 resistor will limit the drive current to about 1.4 mA.
Where high-speed actuation is desirable, use a lower value
resistor for R
required with the LH1525 relay.
R
high output (V
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
