Power Management Integrated Circuits (PMICs) are integrated circuits (ICs) that stabilize, maintain and control the power supply, voltage and current levels in an electronic system. PMICs are optimized for specific applications such as embedded systems, portable consumer devices and systems for industrial, automotive and power management. Hot Swap Controllers are PMICs that are optimized for use in applications where board, card or system is hot plugged, hot swapped or over-loaded.

The HIP1020CK-T is a Hot Swap controller produced by International Rectifier, designed to drive and protect power rails in applications where hot plugin capability is required. This controller is optimized to drive high efficiency, high power SPMOs and PMOs, by providing fast turn-off current limit and accurate current limit protection. It has an enable pin with push-pull outputs, making it capable of driving large loads directly. It also features a watchdog reset and active flyback, which enables its use as an auxiliary power supply.

The HIP1020CK-T has a number of features that make it suitable for hot swap applications. It has a low-voltage control voltage range for active current limit control, allowing the controller to maintain the average output current limit set point over different operating voltages. This helps to maintain system performance during hot swapping. It also incorporates precision monitoring of current and voltage, which allows for precise control over the total demand current. This helps to ensure that the system is not overloaded when hot swapping.

The HIP1020CK-T also has an output voltage regulation feature, which helps to maintain a constant output voltage when the load current is changing. This helps to ensure that the system operates correctly even when there is a high current transient. It also has an integrated comparator to detect an over-voltage condition, which helps to protect the system against over-voltage conditions caused by hot swapping. Finally, it has an integrated charge pump for start-up and active flyback, which allows the controller to monitor current and voltage more accurately during the hot swapping process.

The HIP1020CK-T has a variety of applications, including powering of processor cores or GPU cores in laptop or desktop PCs. It is also used in power supplies, embedded systems and industrial applications, where it is used to ensure that the system is not overloaded when hot swapping. It can also be used in automotive applications, where it is used to protect against over-voltage conditions when powering high power rail loads.

In summary, the HIP1020CK-T is an IC specifically designed for Hot Swap applications that provides fast turn-off current limit and accurate current limit protection, as well as voltage regulation and over-voltage protection features. Its features make it suitable for powering processor cores and GPU cores in laptops and desktop PCs, embedded systems and power supplies. It also has a variety of applications in automotive, industrial and other power rail applications, where it is used to ensure that the system is not overloaded when hot swapping.
