Optoisolators are a type of electrical component used to provide electrical isolation between two circuits. They are used in a variety of applications, from automotive industry to consumer electronics. The ACPL-2670L is an optoisolator that provides electrical isolation and logic output most commonly used in industrial, automotive and consumer electronics. In this article we will look at the applications field and working principle of the ACPL-2670L.

Applications Field of ACPL-2670L

The ACPL-2670L is a high performance and low cost logic output optocoupler, suitable for a wide variety of applications. It is designed to provide electrical isolation between a control circuit and a load circuit. It has a maximum operable voltage of up to 28V and can handle a wide range of load currents ranging from 5mA to 250mA. This optocoupler is also capable of pro-viding a high speed data transfer rate of up to 16Mbit/s.

In automotive applications, the ACPL-2670L can be used for electronic control unit to peripheral communication. It is used to transmit digital information such as engine control information between the control unit and the peripheral. The ACPL-2670L also has extensive industrial applications in areas such as motor drive and protection, factory automation and security systems. In consumer electronics, it is used for controlling LEDs, switching small DC motors, driving LED displays and controlling solenoid valves.

Working Principle of ACPL-2670L

The ACPL-2670L is a logic output optoisolator and it works on the principle of photocoupling. It is composed of a light-activated switch and an output circuit. This optocoupler operates in two steps. In the first step, a control voltage is applied to the LED in the optococoupler and light is emitted. In the second step, the emitted light is detected by a phototransistor, activates the transistor and a logic output is generated. The generated output can be either a high level logic signal or a low level logic signal depending on the voltage applied.

The working principle of the ACPL-2670L can be easily understood by imagining the two parts of the optocoupler as two chambers separated by an opaque wall which means that no electrical connection exists between them. Light is emitted from one of the chambers and when it reaches the other chamber, it activates the phototransistor, providing an output logic signal.

The transmitted data from one side is also completely isolated from the other side ensuring that the transmitted data is secure and not affected by any external interference. The optocoupler also generates a high isolation voltage allowing it to provide maximum electrical isolation between the two sides.

Conclusion

The ACPL-2670L is an optocoupler that provides electrical isolation and logic output. It is a high performance and low cost solution for a wide variety of applications, ranging from automotive industry to consumer electronics. It operates on the principle of photocoupling, providing maximum electrical isolation between the two sides while also transmitting data securely.
