HCPL-7860-000E is a product of Avago Technologies, a provider of analog and mixed signal products. It is a General-Purpose Current Sink device, suited for applications in industrial, automotive and consumer markets. The device is designed to provide output current, sink, and provide isolation for hot-swap power supplies and other power supply systems.

Introduction

HCPL-7860-000E is a fully isolated AC/DC isolated power sink device. It offers an isolated voltage supply and isolated output current with good isolation performance. The device offers very low output resistance and is ideal for applications requiring high output current drive capability. The device is well-suited for applications such as hot-swapping of power supplies, overall power supply sequencing, and overcurrent protection in industrial, automotive and consumer products.

Application

The HCPL-7860-000E is an ideal device for AC/DC isolated power sink applications. It is well-suited for applications such as hot-swapping of power supplies, overall power supply sequencing, and overcurrent protection in consumer and industrial products. The device is designed to be used in a wide range of industrial and consumer applications such as fluorescent lighting, LCD and Oled TV receivers, and enhanced consumer appliance control in homes and cars. The device also features current sink capability up to 7.8A (with 3.3V supply), low output resistance and good temperature junction performance.

Working principle

The working principle of the HCPL-7860-000E is very simple. The device is powered by an AC/DC converter that uses a transformer or flyback application to convert incoming AC or DC power to regulated 12V power. The current sinking circuit employs a low impedance output driver to safely sink current up to 7.8A. The device features a built-in protection circuit that limits the output current to a safe value, based on the electrical break off current point of the chip. When the output current reaches this point, the device will shut down, thus avoiding any overcurrent condition and protecting the device from damage.

Conclusion

In conclusion, the HCPL-7860-000E is a General-Purpose Current Sink device, well-suited for power supply applications such as hot-swapping of power supplies, overall power supply sequencing, and overcurrent protection in industrial, automotive and consumer products. It offers an isolated voltage supply, isolated output current with good isolation performance, very low output resistance and current sink capability up to 7.8A, in addition to its built-in protection circuit which limits the output current to a safe value. With these features, the HCPL-7860-000E is ideal for a variety of applications in the fields of industrial, automotive and consumer products.
