MAX5923EUP+T is a Power Management Integrated Circuit (PMIC) device, specifically classified as a Hot Swap Controller. It features a wide variety of functions and features that deliver cost-effective performance, high efficiency, and reliable operation. The MAX5923EUP+T operates as a Hot Swap controller for low-current Hot Swap applications, consistently managing transient surges or inrush current of up to 24V.

In its specific application field, the MAX5923EUP+T provides the user with Hot Swap control and protection for many different types of low-current DC-DC power converters from 1A up to 44A. It also offers low-voltage FETs for overvoltage protection and adjustable fault thresholds, as well as standard ICs for a very efficient design. As such, it can be used broadly for board-level protection, circuit protection, and array power conversion.

Working Principle: The MAX5923EUP+T combines several safety features into one circuit, allowing the user to customize their application-specific protection requirements. It contains both logic-controlled power control and active power protection, delivering both inrush current protection during initial power-up and overcurrent protection during operation. Additionally, it utilizes a dual-coil low-side MOSFET that can handle up to 24V load busses will fulling comply with USB Type-C and DPPT specifications. Subsequently, the up-channel MOSFET is used to control the current to the load, while an integrated voltage sense amplifier and comparator are used to monitor the voltage and take appropriate action when fault conditions are detected.

Furthermore, the MAX5923EUP+T also features additional ESD protection, RF suppression filters, and an integrated start-up delay timer, allowing its applications to function over a wide range of environmental conditions.

The MAX5923EUP+T combines all of these features into a 8-pin operating temperature range of -50 to 125℃ - reducing the need for additional components and providing high-efficiency power conversion with minimal power losses. As such, it is ideally suited for low-current Hot Swap applications, as it combines all of the critical safety features into a single integrated circuit.

In summary, the MAX5923EUP+T is a feature-rich Hot Swap Controller. Its broad operating temperature range, current-sensing capabilities, multiple power-control functions, and integrated ESD and RF protection filters make it ideal for powering low-current Hot Swap applications, such as board-level protection, circuit protection, and array power converters.
