ISL6150CBZ-T is a Hot Swap controllers and is part of the Hot Swap controllers product line within the Power Management and Custom Solutions division of Intersil. This controller is used to provide reversible current to hot swap circuits in a safe, fault tolerant manner without damage to the system or component.

A hot-swap circuit allows any DC device to be inserted or removed in a live, powered system. The circuit is designed to limit inrush current and thereby prevent damage to the system or component from high currents caused by short circuits, incorrect wiring, or component or component solder failure. A hot swap controller minimizes power dissipation in the system, reducing the size of heat sinks or the components connected to them.

The ISL6150CBZ-T hot swap controller serves three functions. First, it limits inrush current to a safe level. Second, it provides reverse current protection for live-sockets or other circuits requiring polarity protection. Third, it provides voltage monitoring to protect against excessive output voltages.

The ISL6150CBZ-T hot swap controller provides a removable voltage monitor and adjustable current limit. It is protected with an adjustable fault timer and adjustable soft-start function, both of which can be adjusted to fit the circuit. The device also includes an active current foldback feature, which reduces the maximum current as the voltage increases, as well as overvoltage protection.

The ISL6150CBZ-T includes several voltage sensing and monitoring features. These include an adjustable undervoltage lockout, cycle-by-cycle current limit, VIN overvoltage protection, overvoltage protection, and a temperature monitor that can be used to shut down the device under excessive heat conditions.

The ISL6150CBZ-T hot swap controller is designed for use in applications requiring highest performance, highest efficiency, and best safety features. Typical applications for this hot swap controller include servers, storage systems, and telecommunications systems.

The working principle of the ISL6150CBZ-T is simple but essential. When the output voltage of a circuit is equal to or higher than its target setting, the controller activates its voltage monitor, enabling an internal MOSFET switch to turn on the hot swap circuit. The internal MOSFET control circuit then provides the necessary current limit, preventing excessive current from damaging the system.

The ISL6150CBZ-T hot swap controller also includes an adjustable soft-start time, which can be adjusted to meet the needs of each circuit. The adjustable soft-start limits the peak current that occurs when the device is first enabled, improving circuit performance and avoiding damage caused by inrush current.

The device also includes an adjustable fault timer, which can be set to detect and terminate the output voltage to prevent a fault from occurring. The adjustable fault timer features a choice of two delay times, allowing for the maximum protection against overcurrent and overvoltage conditions.

The ISL6150CBZ-T hot swap controller is an integrated, high performance, power management solution for hot swap applications. This device enables high efficiency, reversibility, and flexibility while offering robust protection against overcurrent and overvoltage conditions. This makes it ideal for applications that require hot-swap protection and reversibility with fast, reliable performance.
