Optoisolators - Logic Output: TLP2362(E) Application Field and Working Principle

Optoisolators, also known as opto-couplers, are usually used in electronic circuits to electrically isolate separate sections or signals. They are essential components in many parts of industrial and consumer electronics, and have a wide variety of different application fields. Optoisolators with logic outputs are especially popular and highly sought after in many electrical, commercial, and industrial applications because of their high performance and efficiency.

The TLP2362(E) is an optoisolator with a logic output, specifically designed for circuit isolation and optical-coupling applications. This device integrates multiple logic input circuits with an LED light source and a light-to-electricity converter. The device meets specifications for Class B conducted conductive noise, emission, and susceptibility. It has a long operating life and requires minimum external components. The TLP2362(E) is available in industry-standard dual-inline packages (DIPs) and leadless packages (LPs).

Application Field

The TLP2362(E) is most suitable for providing a logic input and electrical isolation in applications such as:

• Motor control
• A/D conversion
• Power supplies
• Local area networks (LANs)
• Telephone modems
• Printers
• Computers
• Robotics
• Security systems

It is also suitable for applications that require high noise immunity, including PLCs, industrial automation, and process control.

Working Principle

The TLP2362(E) device consists of an LED light source and a light-to-electricity converter, separated by an optical interface. The LED emits a light beam when current is applied, which is connected to the upper terminal of the optoisolator. The light beam travelling through the optical interface is then detected by the phototransistor. When a current is applied to the lower terminal, the phototransistor turns on and the logic output signal is generated. This technology is extremely useful for providing electrical isolation between two circuits.

The TLP2362(E)\'s high voltage characteristics protect the device from damage in the event of miswiring, power transients, and overcurrent conditions.

In addition, the TLP2362(E) features a wide operating temperature range from -25°C to +85°C. This versatility makes it more tolerant of temperature-related noise such as latching noise, and allows for longer life of the device.

The TLP2362(E) provides excellent performance and flexibility in applications which require circuit isolation. The device offers a high-performance level and enables precise and efficient logic input for many industrial, commercial, and electrical applications.
