ISL61853KIRZ-T

The ISL61853KIRZ-T is a Hot Swap Controller which provides passive current limited over-temperature protection for board level devices. It monitors an input voltage and limits the load current when the voltage exceeds an adjustable level. The device also provides over-temperature protection and battery backup for Hot Swap applications.

A Hot Swap Controller is used to regulate and control the power supplied to and from a load. The goal is to protect both the load and the power source from damage due to excessive current or voltage. The ISL61853KIRZ-T provides an adjustable current limiting function, allowing the user to configure the threshold current at which the load will be limited. The controller also provides over-temperature and battery backup protection, ensuring the load is not damaged when exposed to excessive temperatures or sudden power loss.

ISL61853KIRZ-T is ideal for applications requiring tight voltage control and current limiting, such as embedded systems, modular systems and industrial automation equipment. The adjustable current limit allows the user to select an appropriate limit current for the intended application, while the temperature protection function eliminates the need for a dedicated thermal shutdown protection circuit. The battery backup feature provides protection when the supply voltage drops below a certain level, preventing catastrophic failure of the load.

The ISL61853KIRZ-T features an adjustable current limit threshold. The threshold can be adjusted from 0.01A to 5.0A by changing the voltage on the VSNS pin. The device also features a toggle switch input which allows the user to manually disable the load. The device monitors the voltages of the input, output and the battery backup lines, and the temperature of the load in order to detect any potential overcurrent or over-temperature conditions.

The ISL61853KIRZ-T provides a comprehensive solution for Hot Swap applications which require current limiting, over-temperature protection and battery backup functionality. The adjustable current limit threshold allows the user to set the maximum current allowed for the application, while the over-temperature protection prevents damages caused by equipment overheating. The battery backup feature ensures that the load is not damaged when the input voltage is suddenly disrupted.
