Powered by ICminer.com Electronic-Library Service CopyRight 2003 2 Each unit contains a light emitting diode (LED), 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 3.6 volts (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 minimizes effects of any variation in optical coupling. Hysteresis is also provided in the buffer for extra noise immunity and switching stability. input boards and other applications where a predetermined input threshold optocoupler level is desirable. The buffer circuit is designed with internal clamping diodes to protect the circuitry and LED from a wide range of over-voltage and over-current transients while the diode bridge enables easy use with ac voltage input. The high gain output stage features an open collector output providing both TTL compatible saturation voltages and CMOS compatible breakdown voltages.

Transient input current duration is 10 µs at 120 Hz pulse repetition rate. Note that maximum input power, PIN, must be observed. 5. Derate linearly above 100°C free-air temperature at a rate of 4.26 mW/°C. Maximum input power dissipation of 195 mW allows an input IC junction temperature of 150°C at an ambient temperature of TA = 125°C with a typical thermal resistance from junction to ambient of θJAi = 235°C/W.

The t PHL propagation delay is measured from the 2.5 V level of the leading edge of a 5.0 V input pulse (1 µs rise time) to the 1.5 V level on the leading edge of the output pulse (see Figure 7). 12. The t PLH propagation delay is measured from the 2.5 V level of the trailing edge of a 5.0 V input pulse (1 µs fall time) to the 1.5 V level on the trailing edge of the output pulse (see Figure 7). 13. Common mode transient immunity in Logic High level is the maximum tolerable dVCM/dt of the common mode Powered by ICminer.com Electronic-Library Service CopyRight 2003 Fig. 9 voltage, VCM, to ensure that the output will remain in a Logic High state (i.e., VO > 2.0 V). Common mode transient immunity in Logic Low level is the maximum tolerable dVCM/dt of the common mode voltage, VCM, to ensure that the output will remain in a Logic Low state (i.e., VO < 0.8 V). See Figure 8. 14. In applications where dVCM/dt may exceed 50,000 V/µs (such as static discharge), a series resistor, RCC, should be included to protect the detector IC from destructively high surge currents. The recommended value for RCC is 240 Ω per volt of allowable drop in VCC (between Pin 8 and VCC) with a minimum value of 240 Ω. 15. D1 and D2 are Schottky diodes; D3 and D4 are zener diodes. 16.

Test Circuit for Common Mode Transient Immunity and Typical Waveforms. 9 Electrical Considerations The HCPL-5760, HCPL-5761, HCPL-576K or 5962-89477 optocoupler has internal temperature compensated, predictable voltage and current threshold points which allow selection of an external resistor, Rx, to determine larger external threshold voltage levels. For a desired external threshold voltage, V± , a corresponding typical value of Rx can be obtained from Figure 10. Specific calculation of Rx can be obtained from Equation (1) of Figure 11. Specification of both V+ and Vvoltage threshold levels simultaneously can be obtained by the use of Rx and Rp as shown in Figure 11 and determined by Equations (2) and (3). Rx can provide over-current transient protection by limiting input current during a transient condition. For monitoring contacts with a relay or switch, the HCPL-5760/1/K, or 5962-89477 combination with Rx and Rp can be used to allow a specific current to be conducted through the contacts for cleaning purposes (wetting current). The choice of which input voltage clamp level to choose depends upon the application of this device (see Figure 3). It is recommended that the low clamp condition be used when possible to lower the input power dissipation as well as the LED current, which minimizes LED degradation over time. Figure 9. Operating Circuit for Burn-In and Steady State Life Tests. detector IC from destructively high surge currents. See note 14 for determination of RCC. In addition, it is recommended that a ceramic disc bypass capacitor of 0.01 µF to 0.1 µF be placed between Pins 8 and 5 to reduce the effect of power supply noise. For interfacing ac signals to TTL systems, output low pass filtering can be performed with a pullup resistor of 1.5 kΩ and 20 µF capacitor. This application requires a Schmitt trigger gate to avoid slow rise time chatter problems. For ac input applications, a filter capacitor can be placed across the dc input terminals for either signal or transient filtering. Either ac (Pins 1, 4) or dc (Pins 2, 3) input can be used to determine external threshold levels. For one specifically selected external threshold voltage level V+ or V-, R x can be determined without use of Rp via In applications where dVCM/dt may be extremely large (such as static discharge), a series resistor, RCC, should be connected in series with VCC and Pin 8 to protect the Powered by ICminer.com Electronic-Library Service CopyRight 2003 V+ - VTH+ (-) (-) Rx = ––––––––– (1) ITH+ (-) Figure 10. Typical External Threshold Characteristic, V± vs. Rx.
