HCPL-3700 - Isolated Voltage/Current Detectors

Download the HCPL-3700 datasheet PDF. This datasheet also covers the HCPL-0370 variant, as both devices belong to the same isolated voltage/current detectors family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key 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.

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 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.
