PMIC (Power Management Integrated Circuit) Hot Swap Controllers provide an efficient way to control the power delivery of board-mounted systems. The ISL61852JIRZ is a high performance Hot Swap Controllers designed for safety and versatility. It provides protection for hot-pluggable loads in a variety of applications and system operating environments, promoting reliable overload and overvoltage protection, while providing extensive control and monitoring options.

The ISL61852JIRZ is a high performance, low cost, Hot Swap controller with a wide input voltage range (10V to 28V). It is designed to protect sensitive board mounted hardware from excessive current, voltage and temperature while providing dynamic system protection and monitoring during hot-pluggable operations. It provides over-voltage, over-temperature, output short circuit and under-voltage/over-current protection functions, along with optional charger integration and I2c monitoring.

ISL61852JIRZ Hot Swap Controllers are suitable for a variety of applications such as computer motherboards, consumer television systems, Industrial automation, industrial control systems, telecommunications systems, and many other board-mounted systems requiring board-mounted protection. Its features include a low quiescent current, excellent light load efficiency, and a wide range of operating desired operating temperature, making it a great choice for hot-plug systems.

Working Principle

The ISL61852JIRZ Hot Swap Controllers provide a wide range of features designed to ensure safe and reliable operation while protecting sensitive board-mounted hardware and circuitry. By monitoring the voltage and current of the system, it can provide dynamic protection against over-voltage, over-temperature, output short circuit and under-voltage/over-current, making it ideal for systems that require hot-swap and plug-and-play capability.

The operating principles of the ISL61852JIRZ Hot Swap Controllers are based on two key concepts: over-voltage protection and over-temperature protection. Over-voltage protection limits the voltage applied to the board-mounted system and prevents the system from being exposed to dangerously high voltages, while over-temperature protection prevents system components from becoming too hot and potentially damaging the board-mounted components.

In addition to the over-voltage and over-temperature protection, the ISL61852JIRZ Hot Swap Controllers also provide output short circuit protection, which prevents the system from being exposed to dangerous currents by limiting the current that can be supplied to the system. The unit also provides under-voltage/over-current protection, which will disconnect the system before it is exposed to dangerously low voltages or dangerously high currents.

The ISL61852JIRZ Hot Swap Controllers also offers optional charger integration, which allows the system to be charged when power is applied, and a I²C monitoring interface that can be used to connect the Hot Swap Controller with other system components and peripherals. This can provide additional protection, as well as provide the system with a means of monitoring the load current, voltage and temperature.

Conclusion

The ISL61852JIRZ Hot Swap Controllers provide an efficient and cost-effective way to protect board mounted electronics from over-voltage, over-temperature, output short circuit and under-voltage/over-current, while providing dynamic system protection and monitoring during hot-pluggable operations. With its wide input voltage range, low quiescent current, excellent light load efficiency and a wide range of operating temperature range, it is a great choice for hot-plug systems.

The ISL61852JIRZ Hot Swap Controllers provide a reliable solution to protecting sensitive electronics against the dangers of high voltages, currents, and temperatures. It also provides an optional charger integration and I²C monitoring to ensure that the system is operating safely and its load is monitored. With its wide range of features and operating temperature, the ISL61852JIRZ Hot Swap Controller is a great choice for hot-plug systems.
