Description

The PS2501-4 optocoupler consists of four independent optocoupler channels, each comprising an infrared LED on the input side and a phototransistor on the output side. When the LED in each channel is forward-biased, it emits infrared light that activates the corresponding phototransistor, allowing current to flow from the collector to the emitter of the phototransistor. This design enables the transmission of electrical signals between circuits while maintaining electrical isolation between them.

Features

  • 4-Channel Isolation: The PS2501-4 offers four optocoupler channels in a single IC package, allowing for the isolation of multiple signals while saving board space.
  • High Isolation Voltage: Provides a high isolation voltage of 5,000 VRMS, ensuring safe and reliable operation in circuits with significant voltage differences between input and output.
  • Compact 16-Pin DIP Package: The IC is housed in a standard 16-pin Dual In-line Package (DIP), making it easy to integrate into various circuit designs.
  • Wide Current Transfer Ratio (CTR): Offers a current transfer ratio (CTR) ranging from 50% to 400%, depending on the specific model and operating conditions.
  • Low Input Current Requirement: The LEDs require low input current, making the IC compatible with a wide range of control circuits, including microcontrollers and logic circuits.
  • Fast Switching Speed: The PS2501-4 has a fast response time, suitable for applications requiring quick signal transmission.
  • RoHS Compliant: The IC is environmentally friendly, meeting lead-free and RoHS compliance standards.

Applications

  • Signal Isolation: The PS2501-4 is used to isolate multiple signals between different parts of a circuit, particularly where isolation is required to prevent interference or protect low-voltage control circuits from high-voltage signals.
  • Multi-Channel Switching Power Supplies: Suitable for providing feedback isolation in multi-channel switching power supplies.
  • Microcontroller Interfacing: Ideal for interfacing microcontrollers with multiple high-voltage circuits, ensuring protection and isolation.
  • Industrial Automation: Used in industrial systems for isolating multiple control signals, protecting equipment from voltage spikes and noise.
  • Data Communication: Employed in communication systems to isolate data lines and prevent ground loops, ensuring signal integrity.
