Introduction to ISL61851BIBZ-T Application Field and Working Principle

The ISL61851BIBZ-T is an integrated hot-swap controller based on the standards of N-channel MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors). This integrated hot-swap controller is specifically designed to reduce the stress that may occur during the removal or insertion of the load into a system or bus. The working principle of this hot-swap controller is primarily based on a two-phase approach wherein the load is controlled using two distinct cycles or phases. This working principle is used to provide optimal protection from over-current scenarios and simultaneously limit inrush current due to the suspension circuit.

Features of the ISL61851BIBZ-T Hot Swap Controller

The ISL61851BIBZ-T hot swap controller integrates many useful features which are essential for the efficient protective performance of the system. This hot-swap controller operates in either single FET or hiccup/auto-retry (AR/HR) modes. It also uses a variable inrush current limiter feature which can be implemented by adjusting the control pins, allowing the controller to start very quickly in single FET and AR/HR operation modes. Other useful features included in this hot swap controller include a soft-start operation, programmable peak current limit, thermal shutdown, adjustable 1.55V & 2.50V enable voltages, power-on reset, enable pull-up, an enable pull-down circuit, current monitoring, and an active current limit.

Target Applications of ISL61851BIBZ-T Hot Swap Controller

The ISL61851BIBZ-T hot-swap controller is primarily designed for use in IT, telecom, and storage equipment applications. It can be applied in a number of other systems such as multichip systems, rack-based systems, and distributed systems. Additionally, this hot-swap controller can be used in power supplies, system and application boards, and embedded systems. Despite the variation in applications and system architectures, the ISL61851BIBZ-T hot swap controller\'s design allows it to be Power-over-Ethernet (PoE) compatible, robust, and reliable.

Conclusion

In conclusion, the ISL61851BIBZ-T hot swap controller is a versatile, integrated power management solution designed to reduce the stress of load insertion and system failure by providing optimal control of the inrush current and peak current limit. This controller is ideal for a wide range of applications, such as telecom, IT, storage, embedded systems, and more. Furthermore, its design ensures that it is compatible with the Power-over-Ethernet standard, making it a reliable and robust power solution for systems of any size.
