• The device provides a minimum CTR of 40%.
• It also provides current leakage from the input and output sides of up to 1 μ A.

Working Principle

The HCPL-7601-500E works by isolating the input side signal from the output side circuitry, reducing the risk of electrostatic discharge (ESD). It does this by using an optocoupler, which contains an LED light source and a photodetector that can regulate the output signals according to the input signals. The LED is connected to the input side of the device, while the photo detector is connected to the output side. When the input signal is applied, a current flows through the LED, producing light, which is then detected by the photo detector. The photo detector then produces an output signal that is determined by the input signal.

Conclusion

The HCPL-7601-500E optocoupler is a high-performance isolator that provides great signal isolation and fast switching speeds. Its applications include motor control, AC control systems, and luminaire power regulation and monitoring. It has a wide range of technical specifications, such as a 8.2 kV withstand voltage, high commonly mode rejection ratio, and a current transfer ratio of up to 40%. The working principle behind the device is also quite simple, as it utilises an LED light source and a photo detector to regulate the output signals.
