Description

The ICPL2602 optically coupled line receiver combines a GaAsP light emitting diode, an input current regulator and an integrated high gain photon detector. The input regulator serves as a line termination for line receiver applications. It clamps the line voltage and regulates the LED current so line reflections do not interfere with circuit performance.
The regulator allows a typical LED current of 8.5mA before it starts to shunt excess current. The output of the detector IC is an open collector Schottky clamped transistor. An enable input gates the detector. The internal detector shield provides a guaranteed common mode transient immunity specification of 1000V/µs. Surface Mount Option Available.

Notes

  1. Bypassing the power supply line is required, with a 0.01µF ceramic disc capacitor adjacent to each isolator. The power supply bus for the isolator(s) should be separate from the bus for any active loads otherwise a larger value of bypass capacitor (up to 0.1µF) may be needed to suppress regenerative feedback via the power supply.
  2. The ICPL2602 is tested such that operation at If minimum of 5mA will provide the user a minimum of 20% guardband for LED light output degradation.
  3. Device considered two-terminaled: pins 1,2,3,4 shorted together and pins 5,6,7,8 shorted together.
  4. The tPLH (tPHL) propagation delay is measured from the 3.75mA point on the trailing (leading) edge of the input pulse to the 1.5V point on the trailing (leading) edge of the output pulse.
  5. The tELH (tEHL) enable propagation delay is measured from the 1.5V point on the trailing (leading) edge of the input pulse to the 1.5V point on the trailing (leading) edge of the output pulse.
  6. CMh (CMl) is the maximum tolerable rate of rise (fall) of the common mode voltage to assure that the output will remain in a high (low) logic state, Vo > 2.0V (Vo < 0.8V).
  7. For sinusoidal voltages, (|dVCM|/dt)max=pi*fCM*VCMp-p.
  8. No external pull-up is required for a high logic state on the enable input.
