LTC4223CDHD-2#PBF

The LTC4223CDHD-2#PBF is a Hot Swap Controller, which is an integrated solution to manage applications requiring battery-backed power recommendations. It contains two independent channels, so that two circuits can be protected simultaneously, reducing the total cost of a solution by decreasing component count and board space requirements. This Hot Swap Controller works by monitoring the voltage or current on a line and regulating the level of current that is output, to maintain a specific voltage or current. The LTC4223CDHD-2#PBF also supports dynamic load capacitance calculations for dynamic loading, a feature that many Hot Swap Controllers are not capable of.

Applications

The LTC4223CDHD-2#PBF is a versatile Hot Swap Controller that can be used in a variety of applications. It is especially useful in applications that require battery-backed power recommendations. Examples include: telecom systems, industrial equipment, medical and healthcare systems, renewable energy systems, energy storage systems, and automotive power systems.

Features and Benefits

The LTC4223CDHD-2#PBF offers a number of features that enable increased functionality in applications. It has high-output-current drive capabilities to support high-current draw applications, as well as adjustable current limit protection through external components. The two independent channels give it the ability to support multiple output voltages. It also features a comprehensive set of power-saving features, including a low-power mode for minimal standby current, and advanced fault management for low-power system operation.

Working Principle

The LTC4223CDHD-2#PBF controls the output voltage or current based on an adjustable current limit setting.
