Texas Instruments TPS2420RSAR Environmental and export classification status description

The Texas Instruments TPS2420RSAR is a hot-swap power manager IC designed to provide controlled voltage and current management in applications that involve adding or removing a power supply without interrupting the functionality of the circuit. It provides over-voltage, under-voltage, and over-current protection, ensuring safe operation in a variety of power applications. Functions 1. Hot-Swap Controller: Enables circuit board components to be added and removed without shutting down the entire system. 2. Current Limiting: Protects against over-current conditions during startup and operation. 3. Over-voltage and Under-voltage Protection: Monitors input voltage and protects the load from input voltage fluctuations. 4. Fault Indicator: Provides a fault signal output to indicate fault conditions like over-current or thermal shutdown. Applications - Telecommunications Equipment: Ensures continuity of power when replacing power supplies. - Servers and Networking Equipment: Provides reliable power management for sensitive electronic equipment. - Industrial Automation: Maintains power supply integrity in industrial control systems. - PCI/PCIe Bus Powered Cards: Supports hot-swappable cards in computing environments. Alternative Parts - TPS2421: Similar hot-swap controls with slightly different protection features. - MAX5957: Another hot-swap controller with integrated features for managing power delivery. - LT4320: Provides alternative current source management and hot-swap functionality. Embedded Modules While Texas Instruments often does not release specific embedded modules for chips as the TPS2420, you can find evaluation modules or development boards (like TPS2420EVM) that allow developers to prototype and test their applications efficiently.
