Introduction

AI Translation

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 achieve lower-current operation, the HCPL-3760 uses a high-efficiency AlGaAs LED that delivers greater light output at reduced drive currents. These devices incorporate a threshold-detecting input buffer IC, allowing threshold levels to be controlled over a wide input voltage range via a single external resistor. The input buffer integrates several features: hysteresis for enhanced noise immunity and switching transient rejection, a diode bridge for compatibility with AC input signals, and internal clamp diodes to protect the buffer and LED against a wide range of overvoltage and overcurrent transients. Since threshold detection is performed prior to driving the LED, variations in the optical coupling from LED to detector have no effect on the threshold level.
