PS2832-4-F3-A

Applications

The PS2832-4-F3-A is a 4-pin optocoupler, with a Gallium-Arsenide-Phosphide LED as the input device and a NPN Darlington phototransistor as the output device. With its compact and integrated package design, the PS2832-4-F3-A is suitable for applications that require protection from input to output. It can be used for isolating different power domains, preventing ground loops, and protecting data signals from the surrounding environment. Moreover, it can also be employed as a non-intrusive means of monitoring the load current.

The PS2832-4-F3-A is specifically designed for low current switching applications. It offers a low-on-state impedance, high-frequency operation and can withstand up to a rated isolation voltage of 5kV RMS. This makes this device very suitable for automotive applications, including industrial diagnostics, control systems, and lighting systems. Additionally, the PS2832-4-F3-A is approved with the IEC-60747-5-5 and EN60747-5-5 standards, making it compatible with various safety standards.

Working Principle

The PS2832-4-F3-A consists of a Gallium-Arsenide-Phosphide LED coupled to the NPN Darlington phototransistor. When voltage is applied to the anode and cathode of the LED, current flows through it, resulting in LED illumination. This light will then be detected by the phototransistor, which induces a current flow through the collector and emitter.

The PS2832-4-F3-A offers an integrated design with a low profile and pull-through contacts to simplify connection. It is designed to operate at high speed, with a propagation delay time of only 4us and a maximum switching frequency of 400KHz. It also offers a low input current of only 1.6mA, allowing for a more energy efficient solution. Additionally, with a low on-state resistance, the PS2832-4-F3-A is ideal for driving high resistance loads.

In conclusion, the PS2832-4-F3-A is a 4-pin optocoupler suitable for items needing protection against environmental disturbances. It features a low-on-state current, high-frequency operation, and superior electrical isolation. The PS2832-4-F3-A is an ideal choice for automotive and industrial applications that require a compact and reliable solution for isolating input and output.
