PMIC (power management integrated circuit) – Hot Swap Controllers is an important electronic device in many electronic systems as it can effectively control and provide secure power supply in systems with or without multiple power sources. ISL61863CCRZ-T is an advanced hot swap controller designed for controlling power distribution and thermal management in servers, industrial and communications equipment, power supplies and other system applications. It features include an adjustable current limit which allows an exact current limit to be configured to prevent high inrush current and overloading of power distributions in system when hot swapping. Furthermore, ISL61863CCRZ-T offers an adjustable ramp rate of current limiting over time to reduce the acoustic EM interference.

ISL61863CCRZ-T is a 3.3V single-channel Hot Swap controller which is designed to protect, drive and monitor power distribution system when there is a insertion or removal of a device. It provides low power on/off sequencing and supervisor control when devices are hot swapped, regulating the maximum inrush current for overload and hot plugging protection. It also offers adjustable ramp rate to reduce the acoustic EM interference during the hot swapping process. The device has an additional 2.5V linear regulator supply which can be used as supply for digital logic to monitor and activate the then channel PMOS Switch, improving customer experience during hot plug procedure. ISL61863CCRZ-T is currently used in power supplies, servers, industrial and communications devices, high-density system and other applications for providing hot swap and over-current protection.

This hot swap controller provides the following features and functions:

• Current Limit and Control: ISL61863CCRZ-T features adjustable current limit that can be preset to limit the inrush current and prevent overload in power distribution system during the hot swapping process.
• Ramp Rate Adjustment: It has adjustable ramp rate which provides protection against acoustic and EM interference. This helps to minimize the noise generated during the hot swapping process.
• Power Monitor & Status: The Hot Swap controller can monitor and control the power status and give out the information in terms of digital signals.
• Overvoltage & Overcurrent Protection: The device is designed to provide overvoltage and overcurrent for better reliability and safety during hot swapping.

ISL61863CCRZ-T is designed for ease of use with its enhanced protection, minimized power losses and easy to configure current limit and ramp rate. With its wide variety of features, this Hot Swap controller is highly suitable for use in power supplies, servers, industrial and communications devices, high-density systems and other applications.

In summary, ISL61863CCRZ-T is a 3.3V single-channel hot swap controller that features adjustable current limit and ramp rate, power monitoring and status. It is designed to provide better reliability and safety during hot swapping process, suitable for use in power supplies, servers, industrial and communications applications, and other types of systems.
