Hot Swap Controllers datasheet and documents for MAX5903AAETT+T

MAX5903AAETT+T

Hot Swap Controllers Overview

The MAX5903AAETT+T is a hot-swap voltage controller designed for safe insertion of circuit cards into live backplanes. It operates within a supply voltage range of +9V to +72V and supports a single channel. The device limits inrush current during startup and provides overcurrent protection via a circuit-breaker function. It features adjustable current limiting and under-voltage lockout (UVLO). The component is housed in a 6-TDFN (3x3mm) surface-mount package and functions within an operating temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

Enables safe hot-plugging into live backplanes without causing power-supply glitches
Limits inrush current to the load during startup sequences
Provides circuit-breaker functionality for overcurrent protection
Eliminates external components except for the required external p-channel MOSFET

Hot Swap Controllers Applications

Hot-pluggable circuit card insertion into live backplanes
Power-supply sequencing improvements
Overcurrent protection for high-voltage DC loads

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'AAE' against official Analog Devices documentation to confirm exact electrical tolerances and package variations. Confirm availability status as distribution data indicates limited or discontinued stock for certain variants. Ensure the external p-channel MOSFET selection matches the controller's drive requirements and voltage ratings.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring simple, robust hot-swap protection for voltages up to 72V. It is suitable for applications needing minimal external component counts while maintaining precise current limiting. Consider the TDFN-6 package constraints for thermal management and PCB layout space compared to larger packages.

Hot Swap Controllers Part Context

This component belongs to the MAX5902/MAX5903 Simple Swapper family from Maxim Integrated, now part of Analog Devices. These controllers are engineered to simplify hot-swap designs by integrating essential protection logic. The family targets industrial and telecommunications equipment where board replacement without system shutdown is critical.
