The ISL61851CIBZ is an integrated circuit from Intersil Corporation. It is a hot-swap controller integrated circuit that is used in a variety of applications including power-over-Ethernet (PoE) systems, electronic displays, servers, storage, and consumer electronics. The ISL61851CIBZ is capable of providing up to 30V at 0.5A of continuous output current, or up to 3V at 3A of peak current, depending on the application.The ISL61851CIBZ is designed to provide two key functions in a hot swap application. First, it provides protection and control of the load connected to it. Second, it acts as a switch that can be used to disconnect the load from the power source in the event of an overvoltage or other fault condition.At its core, the ISL61851CIBZ is a linear regulator that uses a proprietary voltage regulation algorithm to maintain a regulated output voltage within a specified range. This voltage is typically regulated to within a few millivolts of a predetermined setpoint under both steady-state and dynamic load conditions. This precise control allows the circuit to easily switch between different load levels while still providing excellent protection against overvoltages.The ISL61851CIBZ also provides several protection and control features. The most important of these is overvoltage protection (OVP). This feature protects against overvoltage by shutting off the power supply if the voltage reaches a predetermined value. This OVP is usually set to operate at around 5V higher than the desired output voltage range, providing a safety margin against the possibility of overvoltages. The ISL61851CIBZ also provides undervoltage and overtemperature protection, as well as an adjustable power fail input.The ISL61851CIBZ is a flexible and reliable solution for hot swap applications. It offers precise voltage control and a high degree of protection to ensure that even the most demanding applications remain safe and reliable. With its simple yet powerful feature set, it is an ideal choice for a wide range of hot swap applications.
