ISL61853FCRZ is a hot swapping controller, one of the most important types of power management integrated circuits (PMIC). Hot swapping controllers are designed for intelligent power delivery, providing for voltage monitoring and control of hot plugging loads, as well as over current protection and other features. The ISL61853FCRZ is particularly suited to a variety of applications and it is this versatility combined with its high performance features that makes it an attractive choice for powering the digital age.

Applications

The ISL61853FCRZ is suitable for a wide range of power supply applications, including distributed power systems, portable and embedded designs, data centers, digital equipment and servers, as well as communications, industrial, automotive and medical equipment. The onboard controller can provide extremely accurate, low-voltage, fault tolerant management to multiple voltages and current up to 48V. As a hot swap controller, it can help protect sensitive equipment from over-voltage, over-current and short-circuit conditions, as well as providing power supply management in the event of an unexpected hot-swapping event.

The ISL61853FCRZ hot swap controller is designed for hot-swap applications in order to monitor the supply voltage and detect any transient events that could potentially damage the load. The controller can protect the load by reducing the output current to protect against short-circuiting and providing deglitching during a load insertion, with a reliable recovery capability in case of an over-current or over-voltage event.

Plug-in/Hot-swap Maintaining

The ISL61853FCRZ hot swap controller helps ensure the system is operational and able to maintain power when devices are plugged in. It does this by monitoring the voltage of all components and providing an accurate voltage regulation during system operations and providing protection for the system from faults and power surges. This voltage monitoring and regulating is critical for hot-swapping, as it allows for efficient system operations and helps ensure the system is resilient to power-related issues.

As a hot-swap controller, the ISL61853FCRZ helps support the power delivery to downstream devices and makes sure they are in compliance with the properly programmed voltage levels. This ensures that the system is always on, even during a power supply interruption, and helps reduce downtime when setting up new systems or working with components that may need to be powered rapidly. The ISL61853FCRZ can monitor and control input current, output current, and input voltage when operating in constant-voltage mode.

Overvoltage and Overcurrent Protection

The ISL61853FCRZ provides protection for both the system and the components it is powering. By monitoring current and voltage levels it can detect any overvoltage or overcurrent events and take appropriate action to ensure system safety. In the event of an overvoltage or overcurrent condition the ISL61853FCRZ can shut down the powered devices and reset when recovered from the condition. It also provides thermal shut down and UVP (Under Voltage Protection) features to protect against damaging voltage conditions.

The ISL61853FCRZ is designed to provide a robust and reliable solution for hot-swap and other power supply needs. With its combination of monitoring, voltage regulation, fault protection and other features its an ideal fit for applications where a reliable power supply is important. It can keep systems operational and protected during unexpected hot-swapping events as well as providing efficient and safe power delivery when setting up new systems or deploying equipment in the field.
