PMIC - Hot Swap Controllers are used to prevent system level damage occurring in case of a reversed power supply connection. This is especially important in scenarios where a live connection to an electronics device needs to be made with no downtime bought by powering off and then powering on the device. Many methods of providing redundant power supplies are in use, each having its advantages and disadvantages. The ISL61853JCRZ-T is one such Hot Swap Controller which provides a safe method of connecting multiple power supply rails while preventing any excess resources being used while doing so.

The ISL61853JCRZ-T is an IC Hot Swap Controller from Intersil suitable for applications with up to 10A of current draw. The controller provides a safe connection for both the power supplied to the device and the ground reference of the device. It does this by monitoring the voltage of the VCC and GND pins for any irregularities which could potentially cause damage. This is the main application field of the ISL61853JCRZ-T.

The working principle of the ISL61853JCRZ-T is based on two stages. In the first stage, the hot swap controller checks the voltage levels at the VCC and GND pins before allowing a connection to be established. This allows the device to make sure that the power being supplied is of the expected quality and reduces the chances of damage to the system due to a power supply issue. In the second stage, the current draw of the system is monitored by the controller to make sure that the power supplied is in the specified range and is not being over-utilized. If a misalignment is detected, the controller will disconnect the power supply and alert the system.

The ISL61853JCRZ-T Hot Swap Controller also offers certain protection features such as reverse current protection and over-temperature protection. The reverse current protection feature prevents the damage from being caused due to a wrong connection being made between the power supply unit and the system. The Over-temperature protection feature ensures that the system is not affected by excessive temperatures which could lead to a system failure.

Overall, the ISL61853JCRZ-T is a Hot Swap Controller designed for applications which require a certain level of protection from power supply issues and unexpected power draw. The controller is small in size and is suitable for use in systems where space is an issue. The protection and monitoring capabilities of the controller make it an ideal choice for applications where safety is of utmost importance.
