HCPL-0370, HCPL-3700, HCPL-3760 Isolated Voltage/Current Detectors Data Sheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product Description Features The HCPL-0370/3700 and HCPL-3760 are voltage/current threshold detection optocouplers. The HCPL-3760 is a low-current version of the HCPL-0370/3700. To obtain lower current operation, the HCPL-3760 uses a high-efficiency AlGaAs LED which provides higher light output at lower drive currents. The devices utilize threshold sensing input buffer ICs which permit control of threshold levels over a wide range of input voltages with a single external resistor. * Standard (HCPL-0370/3700) and low input current (HCPL3760) versions The input buffer incorporates several features: hysteresis for extra noise immunity and switching immunity, a diode bridge for easy use with ac input signals, and internal clamping diodes to protect the buffer and LED from a wide range of over-voltage and over-current transients. Because threshold sensing is done prior to driving the LED, variations in optical coupling from the LED to the detector will have no effect on the threshold levels. * AC or DC input * Programmable sense voltage * Hysteresis * Logic compatible output * Thresholds guaranteed over temperature * Thresholds independent of LED optical parameters * Recognized under UL 1577 and CSA approved for dielectric withstand proof test voltage of 3750 Vac, 1 minute Applications * Limit switch sensing * Low voltage detector * AC mains and DC link voltage detection Functional Diagram * Relay contact monitor AC 1 8 VCC DC+ 2 7 NC DC- 3 6 VO AC 4 5 GND * Relay coil voltage monitor * Current sensing * Microprocessor interfacing TRUTH TABLE (POSITIVE LOGIC) INPUT OUTPUT H L L H HCPL-3700 Functional Diagram CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD. The HCPL-0370/3700's input buffer IC has a nominal turn on threshold of 2.5 mA (ITH +) and 3.7 volts (VTH +). The buffer IC for the HCPL-3760 was redesigned to permit a lower input current. The nominal turn on threshold for the HCPL-3760 is 1.2 mA (ITH +) and 3.7 volts (V TH +). The high gain output stage features an open collector output providing both TTL compatible saturation voltages and CMOS compatible breakdown voltages. By combining several unique functions in a single package, the user is provided with an ideal component for industrial control computer input boards and other applications where a predetermined input threshold level is desirable. Ordering Information HCPL-0370/HCPL-3700/HCPL-3760 is UL Recognized with 3750 Vrms for 1 minute per UL1577 unless otherwise specified.

Transient input current duration is 10 s at 120 Hz pulse repetition rate. Note that maximum input power, PIN, must be observed. 4.Derate linearly above 70C free-air temperature at a rate of 4.1 mW/C (HCPL-3700/3760) and 3.1 mW/C (HCPL-0370). Maximum input power dissipation of 230 mW (HCPL-3700/3760) and 172 mW (HCPL-0370) allows an input IC junction temperature of 125C at an ambient temperature of TA = 70C. Excessive PIN and TJ may result in IC chip degradation. 5.Derate linearly above 70C free-air temperature at a rate of 5.4 mW/C (HCPL-3700/3760) and 5 mW/C (HCPL-0370). 6.Derate linearly above 70C free-air temperature at a rate of 3.9 mW/C (HCPL-3700/3760) and 1.9 mW/C (HCPL-0370). Maximum output power dissipation of 210 mW (HCPL-3700/3760) and 103 mW (HCPL-0370) allows an output IC junction temperature of 125C at an ambient temperature of TA = 70C. 7.Derate linearly above 70C free-air temperature at a rate of 0.6 mA/C. 8.Maximum operating frequency is defined when output waveform Pin 6 obtains only 90% of VCC with RL = 4.7 k, CL = 30 pF using a 5 V square wave input signal. 9.All typical values are at TA = 25C, VCC = 5.0 V unless otherwise stated. 10. The tPHL propagation delay is measured from the 2.5 V level of the leading edge of a 5.0 V input pulse (1 s rise time) to the 1.5 V level on the leading edge of the output pulse (see Figure 10). 11. The tPLH propagation delay is measured from the 2.5 V level of the trailing edge of a 5.0 V input pulse (1 s fall time) to the 1.5 V level on the trailing edge of the output pulse (see Figure 10). 12.Common mode transient immunity in Logic High level is the maximum tolerable (positive) dVCM/dt on the leading edge of the common mode pulse, VCM, to insure 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 (negative) dVCM/dt on the trailing edge of the common mode pulse signal, VCM, to insure that the output will remain in a Logic Low state (i.e., VO < 0.8 V). See Figure 11. 13.In applications where dVCM/dt may exceed 50,000 V/s (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 y per volt of allowable drop in VCC (between Pin 8 and VCC) with a minimum value of 240 y. 14.Logic low output level at Pin 6 occurs under the conditions of VIN V TH+ as well as the range of VIN > V TH- once VIN has exceeded V TH+. Logic high output level at Pin 6 occurs under the conditions of VIN V TH- as well as the range of VIN < V TH+ once VIN has decreased below V TH-. 15.AC voltage is instantaneous voltage. 16. Device considered a two terminal device: Pins 1, 2, 3, 4 connected together, and Pins 5, 6, 7, 8 connected together. 17. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage 4500 V rms for 1 second (leakage detection current limit, Ii-o 5 A). 18. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage 6000 V rms for 1 second (leakage detection current limit, Ii-o 5 A).

Typical external threshold characteristics, V vs. RX. 13 For interfacing ac signals to TTL systems, output low pass filtering can be performed with a pullup resistor of 1.5 kW and 20 F 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. Figure 13. External threshold voltage level selection. Either ac (Pins 1, 4) or dc (Pins 2, 3) input can be used to determine external threshold levels. Electrical Considerations For one specifically selected external threshold voltage level V+ or V-, RX can be determined without use of RP via The HCPL-0370/3700/3760 optocouplers have 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 12. Specific calculation of RX can be obtained from Equation (1). Specification of both V+ and V- voltage threshold levels simultaneously can be obtained by the use of RX and RP as shown in Figure 13 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 of a relay or switch, the HCPL0370/3700/3760 in 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 1). It is recommended that the low clamp condition be used when possible. The low clamp condition in conjunction with the low input current feature will ensure extremely low input power dissipation. 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 detector IC from destructively high surge currents. See Note 13 for determination of RCC. In addition, it is recom mended that a ceramic disc bypass capacitor of 0.01 F be placed between Pins 8 and 5 to reduce the effect of power supply noise.

If the denominator of equation (2) is positive, then V+ V TH+ V+ - V TH+ ITH+ and < V- V TH- V- - V TH- ITHConversely, if the denominator of equation (2) is negative, then V+ V TH+ V+ - V TH+ ITH+ and > V- V TH- V- - V TH- ITH V TH- (V+) - V TH+ (V-) RX = ITH+ (V TH-) - ITH- (V TH+) (2) V TH- (V+) - V TH+ (V-) RP = ITH+(V--V TH-)+ITH-(V TH+-V+) (3) www.avagotech.com Avago, Avago Technologies, and the A logo are trademarks of Avago Technologies in the United States and other countries.
