Optoisolators - Logic Output: HCPL-063N-000E application field and working principle

Optoisolators are used to manage the interference of electromagnetic radiation. They are also known as optocouplers or optical isolators. Their primary use is to provide electrical isolation between input and output without affecting signal integrity. The HCPL-063N-000E optocoupler is a logic output optoisolator and is a high performance, low-cost, single-channel device that provides electrical isolation and feature a high dV/dt rating of 1500 V/µs.

The HCPL-063N-000E is a light-activated coupled Module (LACM) optoisolator ideal for logic applications that require 1 dedicated input and 1 dedicated output. It consists of an LED input module coupled to an integrated photosensitive detector. It has a high insulation voltage (2500 Vrms) and 1500 V/µs transient immunity ratings. It features a dedicated input logic (0 or 1) and a logic output voltage with a wide operating supply voltage range of 2.3 to 5.5 V.

Application Fields

The HCPL-063N-000E logic IC is used widely in various applications requiring electrical isolation and low feature-set. It is particularly useful in instrumentation and medical care, allowing off-board device connections while retaining electrical isolation. The HCPL-063N-000E is also suitable for high-reliability industry grade applications such as process control and power monitoring. Its wide operating voltage range and high isolation voltage makes it an ideal choice for many industrial applications.

Working Principle

The HCPL-063N-000E optocoupler is optically linked, and hence provides electrical isolation between the input and output. The LED input module is powered through the input logic and it activates the associated photosensitive detector. An internal Schmitt trigger is used to allow for hysteresis, which increases the noise immunity of the device. It is a wide swing optoisolator, meaning that the output voltage swings from a lower state (low voltage) to a higher state (high voltage). The logic output voltage is equal to the supply voltage when the input logic is at a high state, and at a low state when the input logic is at a low state.

The HCPL-063N-000E is a actively driver optoisolator that utilizes a current source with a specific turn-on and turn-off time feature to activate the internal output transistor. This allows the output state to be determined quickly and accurately with a minimal power budget. It also utilizes a reverse input protection feature to protect the device from damage from reverse polarities. The reverse polarity input protection also increases the reliability of the device and eliminates ambiguity when it comes to performance.

The HCPL-063N-000E optocoupler is offered in a SOIC-8 package for convenient mounting and can operate over a wide temperature range of -40 to +85°C. It also features a high transient immunity level of 1500 V/µs, which makes it an ideal choice for electrical isolation in applications such as high-reliability industry grade applications.

Conclusion

The HCPL-063N-000E optoisolator is an excellent choice for logic applications requiring electrical isolation and low feature-set. It provides high dV/dt rating, high insulation voltage, wide operating supply voltage range, and a wide range of operating temperature. It has a low cost and is easy to mount due to its SOIC-8 package. It is a highly reliable optoisolator also providing features such as reverse polarity protection and transient immunity for improved performance.
