The ISL61861GIBZ-T is a Hot Swap Controllers integrated circuit developed by Renesas. It is designed specifically for use in hot swap applications, where it provides safe and reliable operation of devices that can be inserted/removed from a live system.

The ISL61861GIBZ-T is created for application in various applications including industrial control systems, automotive, consumer products and many other products. It has three main functionalities. First of all, it monitors the inrush current and provides soft start-up of the controleld circuit on a system power-on reset. Second, it controls the output current of the load and restricts the load voltage in order to minimize the effect of over temperature. Third, it\'s operates in a penalty-free fashion by automatically detecting errors in system load and providing a compensative behavior to keep the system stable.

The ISL61861GIBZ-T features a cycle-by-cycle current limit and a monitoring of the load voltage which provide a robust protection against overload and short circuit conditions. Moreover, its has a selectable fast or slow rise time allows for optimal response to fault currents and faster system recovery. It also permits output current monitoring without an external sense resistor. The ISL61861GIBZ-T simplifies the design of hot swap systems by using an adjustable current sense level and allows for the adjustment of current limit and output voltage levels.

The Hot Swap Controller utilizes a buck converter architecture for regulator operation with adjustable output voltage in soft-start mode. The input voltage is limited to high compliance levels and therefore prevents system damage. At the same time, the internal multi-protection fault detect logic ensures an immediate shutdown of power in case of any fault. The fault conditions are both open loop and short circuit, The Hot Swap Controllers protection logic is extended by applying additional circuit protection making it suitable for use in safety critical applications such as automotive, industrial control systems and consumer products.

The Hot Swap Controllers enables fast and reliable control of the output voltage and current limiting. It provides a cost effective solution for managing inrush current and over temperature conditions and thus allows product designers to create more reliable hot swap systems that can be used in a wide range of applications. The Hot Swap Controllers also provides an adjustable soft-start feature and includes monitoring of the output and input voltages to provide protection against overload, short circuit and temperature. With such a highly integrated and robust designs, the Hot Swap Controllers are the perfect choice for applications requiring safe and reliable hot swap operation.
