ISL61853NIRZ is a highly integrated hot-swap controller designed for advanced systems requiring AC/DC, hot-swap, and over voltage protection facilities. The ISL61853NIRZ is capable of detecting over-voltage, inverter-driven systems, and preventing or limiting the voltage from rising to a dangerously high level by responding quickly and controlling the power supply. The power management integrated circuit contains all the necessary components for controlling the AC/DC and hot swap circuits. In addition, the ISL61853NIRZ is equipped with an integrated Load Current Detection Circuit to detect the presence of a load current and enable reactive protection of the system.

ISL61853NIRZ is an ideal solution for applications requiring hot-swap, AC/DC power, over voltage protection and load current detection. The integrated Load Current Detection Circuit limits over-voltage peaks, ensuring system safety and reliability. The ISL61853NIRZ is compliant with the IEC 60950-21 and is suitable for applications where IEC 60950-21 requirements are mandatory. In addition, the ISL61853NIRZ has a low quiescent current of just 16 uA, making it suitable for use in power sensitive applications.

When the load current is detected, the ISL61853NIRZ hot swap controller turns on the power and limits the output current. At the same time, the hot swap controller will monitor the voltage and hibernate the circuit if the voltage exceeds the over-voltage threshold or if the load current exceeds the limit. The over-voltage protection circuit ensures that the system is not damaged due to excessive current flow. Once the over-voltage condition has been corrected, the hot-swap controller will allow the load to be re-powered.

The ISL61853NIRZ also has a wide array of protection features including over-current, over-temperature, and short-circuit protection. The integrated amplifier and comparator are used to sense the load current and enable effective over-current protection. The over-temperature protection prevents the system from operating at dangerous temperatures. The integrated short-circuit protection circuit prevents the system from damaging due to sudden high current flow.

The ISL61853NIRZ hot swap controller is suitable for use in applications such as servers and storage subsystems, and communication systems requiring hot swap, over voltage and load current protection. The integrated features of the controller ensure that the system is safe, reliable and cost effective. The ISL61853NIRZ can be combined with other power management devices to provide a complete solution for a variety of applications.
