Introduction:

The ISL61853KCRZ-T, a highly integrated power management integrated circuit (PMIC) designed specifically to provide hot swap protection, is a critical component in a wide range of applications such as communications and networking, industrial, and data storage systems.

Application Field:

The ISL61853KCRZ-T is used in a variety of applications where hot swap protection is required, including: communication and networking systems, industrial equipment, data storage systems, and appliance equipment. The IC helps to reduce overall system cost by providing enhanced level of system protection, while eliminating the need for external fuse protection. In addition, it can also reduce the need for additional external components, such as sense resistors, TVS diodes, and current limit devices.

The built-in advanced protection features include input over-voltage, over-temperature, current, and voltage protection features that allow for safe and reliable hot swap events. It can also include advanced fault diagnostic features for monitoring system faults.

Working Principle:

The ISL61853KCRZ-T employs three key components to enable safe hot swap events. First, it uses an advanced current limiting protection circuit to limit the current drawn from the source while protecting the source from over-current and over-voltage faults. Second, the hot swap controller implements an accurate over-temperature protection circuit to protect the system from thermal overload. Third, the integrated thermal shutoff prevents further damage to the system by automatically shutoff the power supply if the temperature reaches an unsafe level.

In addition, the ISL61853KCRZ-T provides a programmable current limit range from 11.5A down to 1.3A. The current limit can be programmed using various external components. This allows system designers to tailor the current limit to the application needs. The device also offers both hysteretic and latching fault outputs which can be used to signal system faults.

The device also includes additional protection features such as transient voltage suppression (TVS) diodes, under voltage lockout (UVLO), over voltage lockout (OVLO), and slew rate control. These protection features make the ISL61853KCRZ-T an ideal solution for hot swap applications where high-current inrush protection and system reliability are required.

In conclusion, the ISL61853KCRZ-T is a highly integrated PMIC designed to provide hot swap protection for a wide range of applications. It is an ideal solution for providing superior protection and reliable hot swap events for communication and networking, industrial, and data storage systems.
