PS2801-4 Typical application Circuitry

PS2801-4

The PS2801-4 is a high isolation voltage, quad optocoupler, which contains four optically isolated channels. Each channel comprises a phototransistor that is optically coupled to an infrared-emitting diode. This type of chip is used to transmit signals between different voltage potentials and impedances while maintaining electrical isolation.

Application Scenarios:

Optocouplers like the PS2801-4 are commonly used in digital signal isolation, signal level shifting, line receivers, power supply regulators, and microprocessor system interfaces. They're particularly critical in situations where high-voltage insulation is necessary, such as in switching power supplies and motor control systems.

Key Parameter Features:

The PS2801-4 offers a high isolation voltage (usually around 5,000V RMS), fast switching speeds, and a small package footprint. Each channel can typically operate with a forward diode current of about 5mA and a collector-emitter voltage of around 35V, with a current transfer ratio (CTR) that is adequate for many low-power applications.

Circuit Connection Example – Microcontroller Interface Circuit:

Infrared Emitting Diode Forward Connection:

- Pin 1 (Anode) and Pin 2 (Cathode) of the first channel are connected to a GPIO pin of the microcontroller and ground, respectively, through a current limiting resistor to control the forward current of the diode.

Phototransistor Output Connection:

- Pin 4 (Emitter) of the first channel is connected to the ground, and Pin 3 (Collector) is connected to the input of the next stage in the circuit, which could be another integrated circuit or a microcontroller pin. A pull-up resistor is typically added between the collector and the supply voltage.

Optical Isolation:

- The physical gap between the diode and phototransistor inside the PS2801-4 chip ensures electrical isolation between the input and output, thereby protecting the low-voltage side from high-voltage transients.

Power Supply Considerations:

- Separate power supplies may be used for the diode and phototransistor sides to maintain isolation. The voltage levels should match the requirements of the microcontroller and the PS2801-4.

Design Considerations:

- Current Limiting Resistor: Calculate the value to limit the forward current of the diode within specifications.

- Input-Output Isolation: Verify that the working voltage and transient voltage spikes do not exceed the isolation rating of the PS2801-4.

- Speed Requirements: Consider the switching speed of the PS2801-4 and ensure it aligns with the signaling speed requirements of your application.

- Output Pull-up Resistor: Choose a pull-up resistor value that allows the phototransistor to saturate when active and provides the correct logic level when inactive.

Using the PS2801-4 in a microcontroller interface circuit underscores its capacity to interface digital signals across varying voltage domains safely. Adhering to the PS2801-4's specified parameters allows for tailored solutions that mitigate risks associated with electrical isolation challenges in sensitive electronic systems.
