PMIC – Hot Swap Controllers are a special type of adapter that provides autonomous power to loads, circuits and other electronics during a hot swap event. Hot swap controllers enable the control and mitigating of any inrush current or current surge with the integration of electronic thermal shutdown and current limiting. This helps with peak current control, reducing unnecessary stress and wear on surge protection components and these controllers are typically used in a variety of industrial, automotive and consumer applications where reliable, autonomous power management is essential.
The ISL61853GIRZ-T is a fully integrated hot swap controller that is designed to transition power without over-heating, providing high functionality and affordability at the same time. This IC is capable of using multiple integrated protection features, including current limiting and thermal shutdown, to regulate the power transition during a hot swap event and protect against any current surges. The ISL61853GIRZ-T controller also features an integrated linear regulator and Constant On-time (COT) architecture, which together provide accurate, efficient and autonomous regulation of the output voltage. This product is available in a thermally enhanced thermally and halogen free, lead 25-lead HTSSOP package, making it ideal for compact designs.
The ISL61853GIRZ-T is designed for use in a variety of applications, including hot swappable PCI Express cards, server power supplies, communication systems, medical equipment, industrial machinery and other high reliability products. When used in conjunction with a synchronous buck converter, the ISL61853GIRZ-T hot swap controller is well suited for providing flexible, autonomous, and accurate power management and control in high power or high reliability systems. The ISL61853GIRZ-T is a reliable, easy to use solution ideal for a wide variety of applications that require autonomous power management.

The ISL61853GIRZ-T hot swap controller features multiple patent pending protection features, including a unique current limiting mechanism, which enables current limiting without sensing the output inductor current. This feature helps protect against system damage due to current surges, ensuring a safe and reliable power transition. The ISL61853GIRZ-T further features an adaptive input overvoltage protection circuit that shuts down the gate drive when the input voltage of the system exceeds specified levels. This feature helps to protect the system from any current overshoots during a hot swap event. Additionally, this controller contains a thermal shutdown feature that is designed to shut down the gate drive when the junction temperature of the IC exceeds a specified threshold. This feature helps to protect the IC from overheating and premature failure in high power or high reliability systems.

Furthermore, the ISL61853GIRZ-T hot swap controller features a low quiescent current, which helps to minimize power usage. This feature is particularly valuable in battery operated applications, or any other portable or low power applications, where power efficiency is critical. The ISL61853GIRZ-T also contains an integrated soft start controller which allows for smooth, adjustable power up of the system at startup. This feature minimizes any inrush current from the start up process, which helps avoid any system damage from any current surges.

Lastly, the ISL61853GIRZ-T hot swap controller features an automatic power fail monitor, which is designed to ensure that the system is shut down properly during a power failure event. This feature helps to prevent any unexpected system damage or data loss that may result from a power failure. All of these features combined make the ISL61853GIRZ-T hot swap controller an ideal solution for any application or system in need of reliable and robust power management.

In conclusion, the ISL61853GIRZ-T hot swap controller is an efficient, reliable, and easy to use solution for providing autonomous power management and control. With its multiple patent pending protection features, low quiescent current, integrated linear regulator, COT architecture, and automatic power fail monitor, the ISL61853GIRZ-T hot swap controller is well-suited for a variety of industrial, automotive, and consumer applications where reliable, autonomous power management is essential.
