PMIC—Hot Swap Controllers refer to a type of power management integrated circuits (PMICs) that help safely control the power in hot swap and power gate applications. In any application where power must travel, it is necessary to endure that the power is delivered in a safe and efficient manner. Hot swap controllers do just that, guaranteeing a safe and reliable connection when the power is connected and then removed, reducing the risk of damage due to mis-wiring and system malfunction. The ISL61863KCRZ is a great example of a Hot Swap Controller, designed to specifically protect against voltage transients commonly seen in hot swap applications.

The ISL61863KCRZ Application Field

The ISL61863KCRZ is a high performance Hot Swap Controller with precision Vin under-voltage detection, adjustable output drive and two integrated high-current gate drivers. Ideally suited for use in server, storage, telecom and industrial systems, it is a high performance, cost effective, and highly integrated solution for Hot Swap and power gate applications. Featuring a wide Vin range of 5V to 24V, the ISL61863KCRZ is an optimal solution for powering rack mount servers and Enterprise Storage systems, as well as low-voltage circuits such as AdvancedTCA and Multi-Procesora. Its integrated integrated high-current gate drivers and adjustable dead-time enable it to support the most demanding server, telecom, storage and industrial applications.

The Working Principle of the ISL61863KCRZ

The ISL61863KCRZ effectively combines two distinct functions in one highly efficient package. First, it monitors the supply voltage (Vin) and limits the inrush current during hot swap applications. Secondly, it provides protection against over currents and voltage transients. The ISL61863KCRZ’s integrated current sensing and high-precision current limit provide protection against high inrush currents while it’s adjustable dead-time and pre-charge circuits support multiple circuits types and dynamically shape the inrush current. Together, these two functions make the ISL61863KCRZ a lifetime-guaranteed hot swap solution for safe, reliable and accurate power delivery.

The features of the ISL61863KCRZ are optimized to protect against both accidental damage from mis-wiring and system malfunction. In terms of accuracy, the device’s precision Vin under-voltage detection circuitry helps protect against under-voltage faults that could potentially damage the connected load. Additionally, it provides adjustable over-current protection and configurable current limit for improved system reliability. And last but not least, it features a programmable dead-time which helps enable predictable current ramp-up times and thus helps ensure safe power delivery.

Conclusion

In conclusion, the ISL61863KCRZ is an advanced and highly reliable Hot Swap Controller designed with safety in mind. It’s state-of-the-art integrated components effectively let it provide protection against both mis-wiring and system malfunction, helping guarantee a secure, accurate, and cost effective power delivery in server, storage, telecom, and industrial systems. Plus, the device’s integrated components result in a highly space-efficient, cost-effective solution that is easy to integrate into existing systems.
