HCPL-0370, Isolated Voltage/Current Detectors

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 devi

* 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
