HCPL-3700-500E

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/cur- Standard (HCPL-0370/3700) and low input current rent threshold detection optocouplers. The HCPL-3760 is (HCPL-3760) versions a low-current version of the HCPL-0370/3700. To obtain AC or DC input lower current operation, the HCPL-3760 uses a high-effi - Programmable sense voltage ciency AlGaAs LED which provides higher light output at lower drive currents. The devices utilize threshold sens- Hysteresis ing input buffer ICs which permit control of threshold Logic compatible output levels over a wide range of input voltages with a single Thresholds guaranteed over temperature external resistor. Thresholds independent of LED optical parameters The input buffer incorporates several features: hysteresis Recognized under UL 1577 and CSA approved for for extra noise immunity and switching immunity, a di- dielectric withstand proof test voltage of 3750 Vac, 1 ode bridge for easy use with ac input signals, and inter- minute nal clamping diodes to protect the buffer and LED from a wide range of over-voltage and over-current transients. Applications Because threshold sensing is done prior to driving the LED, variations in optical coupling from the LED to the Limit switch sensing detector will have no effect on the threshold levels.

TH TH 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 (I +) and 3.7 volts (V +). TH TH The high gain output stage features an open collector output providing both TTL compatible saturation voltages and CMOS compatible break down voltages. By combining several unique functions in a single package, the user is provided with an ideal component for indus- trial control computer input boards and other applications where a pre deter mined input threshold level is desirable.
