Hot Swap Controllers datasheet and documents for MAX5902LAETT+
Hot Swap Controllers Overview
The MAX5902LAETT+ is a hot-swap controller designed for safe insertion of circuit cards into live backplanes without causing power-supply glitches. It operates within a +9V to +72V supply range and requires only an external p-channel MOSFET, eliminating the need for an external sense resistor. The device limits inrush current during startup and provides a circuit-breaker function for overcurrent protection. It features adjustable undervoltage lockout, a power-good output rated for +72V, and thermal shutdown to protect the external MOSFET.
Hot Swap Controllers Feature Summary
- Eliminates external sense resistors by integrating current limiting
- Provides latching or automatic retry fault management options
- Includes ON/OFF input for load power-supply control and sequencing
Hot Swap Controllers Applications
- Network routers
- Servers
- RAID systems
Hot Swap Controllers Procurement Notes
Verify the specific suffix 'ETT' against the manufacturer's official datasheet to confirm package type and electrical characteristics. Confirm RoHS compliance status and lead times with authorized distributors, as availability may vary. Ensure the external p-channel MOSFET selection matches the controller's drive capabilities and voltage ratings.
Hot Swap Controllers Selection Notes
Select this component when designing hot-swap circuits for high-voltage backplanes up to 72V. It is suitable for applications requiring simplified bill-of-materials due to the absence of sense resistors. Consider the available fault management modes and thermal protection requirements when evaluating suitability for industrial or server environments.
Hot Swap Controllers Part Context
The MAX5902 belongs to Maxim Integrated's Simple Swapper family of hot-swap controllers. This series focuses on providing robust protection for circuit cards during insertion into live systems. The MAX5902 variant specifically targets applications needing wide input voltage ranges and integrated current limiting without external sensing components.
