PS2801-4-A Typical application Circuitry

PS2801-4-A

The PS2801-4-A is a high isolation voltage, quad optocoupler. Optocouplers, sometimes referred to as opto-isolators, are parts that communicate electrical signals between two isolated circuits by light. Each of the four optically isolated channels on the PS2801-4-A is made up of a phototransistor and a gallium arsenide infrared LED.

Application Scenarios:

Optocouplers like the PS2801-4-A are used in a variety of applications where signal transfer needs electrical isolation. Common scenarios include industrial control systems, power supply circuits, digital telecommunications, and signal transmission between different voltage domains.

Key Parameter Features:

- Isolation Voltage: Typically up to several thousand volts (3750Vrms for PS2801-4-A).

- Current Transfer Ratio (CTR): Ratio of output current to input current, indicative of the efficiency of the optocoupling process.

- Propagation Delay: The amount of time an optocoupler needs to process a signal.

- Package: Surface-mount package options are available, allowing for compact circuit designs.

Circuit Connection Example – Isolated UART Communication:

Power Supply for LEDs:

The anodes of the infrared LEDs (pins 1, 3, 5, and 7) should be connected to a positive power supply through current-limiting resistors, while the cathodes (pins 2, 4, 6, and 8) are connected to the transmitting UART lines.

Phototransistor Output:

The collectors of the phototransistors (pins 11, 13, 15, and 17) are connected to a positive supply voltage, while the emitters (pins 12, 14, 16, and 18) will be connected to the receiving UART lines through pull-down resistors.

Current-Limiting Resistors:

Place current-limiting resistors in series with the LEDs to prevent exceeding the maximum forward current rating.

Input Signal:

The input UART signals are to be connected to the anodes of the LEDs through series resistors, ensuring the forward voltage and current are within the specified limits of the PS2801-4-A.

Pull-down Resistors:

Connect pull-down resistors to the emitters of the phototransistors to establish a low level when the LED is off.

Design Considerations:

- Isolation Requirements: Verify that the working voltage and transient overvoltage conditions are within the isolation specifications of the PS2801-4-A.

- Data Rate: Ensure the propagation delay of the PS2801-4-A is suitable for the UART communication speed.

- Power Dissipation: Consider the power dissipation across the current-limiting resistors and ensure it is within safe limits.

- Ambient Light: Shield the optocoupler from ambient light to prevent erroneous signals.

- Temperature: Be aware of the operating temperature range and derating factors for the PS2801-4-A.

Incorporating the PS2801-4-A into an isolated UART communication circuit demonstrates the device's ability to provide electrical isolation while maintaining signal integrity across different voltage domains. Utilizing the PS2801-4-A ensures that communication between parts of a system is both safe and reliable, especially in environments where electrical isolation is paramount.
