Optoisolators are components used to ensure electrical isolation between two circuits or provide an interface between them. The optoisolator range includes components for signal amplifying, switching as well as logic-level translating functions. The TLP185(BLL-TPR,E) optoisolator belongs to the type with transistor, photovoltaic output; its application field and working principle are described in the following.

TLP185(BLL-TPR,E) is a very small and high-speed optoisolator that is used in a wide range of applications. It is mainly used in industrial control and computer systems for providing galvanic isolation between two devices with different parameters. It can also be used in telecommunication systems, power electronics, instrumentation systems, and other types of applications. It provides an isolation of more than 100MΩ between input and output pins due to its built-in thyristor output stage.

This optoisolator features a built-in, high-quality phototransistor output with a voltage gain of 30V/V. Its optimized design ensures an excellent pulse response and high reliability. The maximum response time is 1µs, and the input and output are monostable. In addition, it provides current monitoring for LED and phototransistor output and overcurrent protection to the IC.

The TLP185(BLL-TPR,E) includes a high-efficiency LED, a photodiode and a phototransistor that are integrated into a single device. The LED output is connected to the photodiode input and the phototransistor is connected to the output for signal conversion. The operation of the optoisolator is relatively straightforward. When the LED is turned on, it produces an output of light which is detected by the photodiode. This then produces a small current in the output circuit, which is amplified by the phototransistor. The amplified signal then drives the output circuit.
