HCPL-3760-000E

The HCPL-3760-000E is a 1-channel 8-pin isolated voltage/current Threshold Detection Optocoupler for use with relay contact monitor and relay coil voltage monitor. 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. 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.

• Programmable sense voltage
• Hysteresis
• Logic compatible output
• Thresholds guaranteed over temperature
• Thresholds independent of LED optical parameters
