This chip is specifically designed to provide superior power supply sequencing and management while also allowing high levels of robustness and functionality. The ISL61862GCRZ is a single-chip solution that provides reliable, efficient and safe control of operating system hot swaps and other high-end power management functions.

ISL61862GCRZ Application Field and Working Principle

The ISL61862GCRZ Hot Swap Controller is ideal for applications requiring efficient power supply sequencing and robust control during high-end hot swaps. It is designed to provide superior power management in systems with a large number of components and high power densities.The ISL61862GCRZ is a single-chip solution for hot swap control that eliminates the need for complex discrete power sequencers. The chip features a built-in differential voltage monitor, a fault detection circuit and a voltage-inrush limiting circuit. The integrated control logic also offers cable length compensation, temperature resistor sensing and reporting, temperature dependent current limit and selectable shut- down voltage levels.In addition, the ISL61862GCRZ Hot Swap Controller also includes a number of protections. Its adjustable current limits can protect against over-load and short-circuit conditions. The chip also includes an optional short-circuit delay that allows the system to establish a valid ground before allowing the power supply to come up.The ISL61862GCRZ Hot Swap Controller also allows for the use of remote LEDs to indicate the operating status of the system. The output pins feature both an active low and active high default setting, allowing the user to selectively disable the remote LEDs.

Conclusion

The ISL61862GCRZ Hot Swap Controller is a powerful and efficient solution for high-end power management applications. It offers superior power supply sequencing and robust protections for systems with a large number of components and high power densities. With the integrated control logic and adjustable current limits, users can achieve safe, reliable and efficient hot swaps in mission-critical applications.
