Introduction

Optoisolators are a type of isolation technology that transmit signals without direct electrical contact between the input and output stages. Transistor, photovoltaic output, optoisolators are used to electrically isolate inputs and outputs in electronic systems. The HCPL-270L-360E is a popular device of such optoisolator category.

Application Field of HCPL-270L-360E

The HCPL-270L-360E is a low power optoisolator designed to operate from a single 5 V supply source. It is a low-cost, high-efficiency optoisolator packaged in an ultra-small leadframe SOIC-8 package, compatible with all major industry formats. The device is suitable for processor/bus isolation from ESD, EMI and other electrical noise. It has a wide range of applications, including voltage conversion, isolation interface, over-current protection, and signal transmission protection.The HCPL-270L-360E is a very useful device in the automotive industry, especially for windscreen control motion control and instrument-panel lighting control applications. Its use for automotive powertrain systems is growing, thanks to its small size and its ability to provide good isolation and thermal protection. The HCPL-270L-360E is also used in industry for switching power supplies, motor control, and energy metering.

Working Principle of HCPL-270L-360E

The HCPL-270L-360E is an optoisolator based on a photovoltaic output transistor. It consists of an infrared LED, an integrated photovoltaic output transistor, and a THINPAK surface-mount plastic package. The LED emits infrared light when it is forward biased. The emitted infrared light is detected by the integrated photovoltaic output transistor which produces an output current that is proportional to the level of irradiance received. The HCPL-270L-360E is designed to operate from a single 5 V power supply. When the power supply voltage is applied, the LED emits optical radiation which is detected by the photovoltaic output transistor, which produces a current flow through the output stage. The output transistor is then able to regulate the output voltage and current. This feature allows for low power consumption and an extended output range.

Conclusion

In summary, the HCPL-270L-360E is an optoisolator ideal for automotive and industrial applications which require a small size, low power consumption, and good isolation performance. Its photovoltaic output transistor operates on a single 5 V supply, and delivers an output current and voltage proportionally to the amount of radiation received. As a result, the HCPL-270L-360E is an ideal choice for applications such as voltage conversion and instrument-panel lighting control.
