ISL6115CB-T

Introduction

ISL6115CB-T is an intelligent hot-swap that allows connection and disconnection of power rails between two power sources. ISL6115CB-T replaces industry’s aging PolyPhase hot-swap controllers, offering superior performance as well as simpler use. It is designed to reduce power supply risk and simplify development design when applied to a wide range of applications such as telecommunications, computing, and embedded systems. This article will discuss the application field of ISL6115CB-T and its working principle.

Application Field of ISL6115CB-T

The ISL6115CB-T is suitable for a wide range of applications including telecommunications, computing and embedded systems that require efficient hot-swapping of internal power rails. ISL6115CB-T can support up to 10A peak current with up to 8.2V voltage tolerance. It is compatible with a variety of low-voltage systems, providing an easy and reliable way to connect and disconnect power rails with little risk of damage to the system. In addition, its adjustable soft-start feature helps reduce in-rush current to prevent supply sequencing violations during initial power up. This device comes in a thermally enhanced 3x5mm TQFN package, making it ideal for applications with size constraints.

Working Principle of ISL6115CB-T

The working principle of ISL6115CB-T involves the following three steps: first, the disable pin triggers the device to latch off in order to disconnect the power rails between the two power sources. Then, a voltage on the enable pin triggers the device to turn on and connect the power rails. Finally, the device checks the voltage on the hot-swap supply and starts the soft-start feature to slowly ramp the output voltage and current to the desired levels according to its management loop.

Conclusion

ISL6115CB-T is a highly efficient hot-swap controller ideal for applications in the telecommunications, computing, and embedded system fields. Its adjustable soft-start feature helps reduce in-rush current to prevent supply sequencing violations during initial power up. It provides an easy and reliable way to connect and disconnect power rails with little risk of damage to the system while also taking up less space than other similar controllers.
