Description
The ICPL3700 is a voltage/current threshold detection optocoupler. This optocoupler uses an internal light
emitting diode, a threshold sensing input buffer IC, and a high gain photon detector to provide an
optocoupler which permits adjustable external threshold levels. The input buffer circuit has a nominal turn-on
threshold of 2.5 mA (Ith+) and 3.8 V (Vth+). The addition of one or more external attenuation resistors
permits the use of this device over a wide range of input voltages and currents. Threshold sensing prior to
the LED and detector elements minimises effects of different optical gain and LED variations over
operating life (CTR degradation). Hysteresis is also provided in the buffer for extra noise immunity and
switching stability. Surface Mount Option Available.
