Description

The HCPL-3700 consists of an input stage with an infrared light-emitting diode (LED) and an output stage with a phototransistor. The device is specifically designed to handle AC or DC input signals and convert them into a digital logic signal with electrical isolation between the input and output. It features built-in circuitry that ensures accurate and reliable signal conversion.

Features

  • AC/DC Input Handling: Capable of handling both AC and DC input signals, making it versatile for various applications.
  • Electrical Isolation: Provides isolation between the high-voltage input and the low-voltage output, typically up to 5000 VRMS, ensuring safety and protection for sensitive logic circuits.
  • Compact DIP-8 Package: The 8-pin DIP package is convenient for mounting on circuit boards and allows for easy integration into electronic systems.
  • Logic-Level Output: Converts AC/DC input signals into standard logic levels (TTL/CMOS), making it suitable for interfacing with digital circuits.
  • Built-In Protection: Includes features such as over-voltage protection and input signal conditioning to enhance reliability and durability.

Specifications

  • Input Voltage Range:
    • AC Input: Up to 400V peak.
    • DC Input: Up to 400V DC.
  • Input LED Forward Voltage: Typically 1.2V (maximum 1.4V) at 20mA forward current.
  • Input LED Reverse Voltage: Maximum 6V.
  • Isolation Voltage: 5000 VRMS.
  • Output Collector-Emitter Voltage (VCEO): Maximum 30V.
  • Output Collector Current (IC): Maximum 20mA.
  • Propagation Delay:
    • Rise Time (tr): Typically 1µs.
    • Fall Time (tf): Typically 1µs.
  • Output Saturation Voltage (VCE(sat)): Maximum 0.4V at IC = 5mA.
  • Operating Temperature Range: -40°C to +85°C.

Applications

  • AC/DC to Logic Interface: Converts high-voltage AC or DC signals to standard logic levels for interfacing with digital circuits.
  • Switch-Mode Power Supplies (SMPS): Used for signal isolation and conversion in switch-mode power supplies.
  • Industrial Control Systems: Provides isolation and signal conversion in industrial automation and control systems.
  • Metering and Monitoring: Suitable for use in equipment that monitors or measures high-voltage AC/DC signals and requires safe and accurate signal conversion.
