Hot Swap Controllers datasheet and documents for MAX5903LAEUT+T

MAX5903LAEUT+T

Hot Swap Controllers Overview

The MAX5903LAEUT+T is a hot-swap controller designed for safe insertion of circuit cards into live backplanes. It operates within a supply voltage range of +9V to +72V and utilizes an external P-channel MOSFET. The device limits inrush current during startup and provides overcurrent protection through a circuit-breaker function. It features adjustable undervoltage lockout (UVLO) and requires no other external components besides the MOSFET, offering a simplified solution for hot-plugging applications without causing power-supply glitches.

Hot Swap Controllers Feature Summary

Enables safe hot-plugging of circuit cards into live backplanes without inducing power-supply glitches
Limits inrush current to the load during startup sequences
Provides circuit-breaker functionality for robust overcurrent protection
Operates with minimal external components, requiring only an external P-channel MOSFET

Hot Swap Controllers Applications

Telecommunications line cards requiring hot-swap capability
Industrial control systems with modular card architectures
Server hardware allowing live board replacement
Test and measurement equipment with hot-pluggable modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'LA' against the manufacturer's official datasheet to confirm the exact pinout and electrical characteristics, as suffixes often denote package or temperature variations. Ensure the external P-channel MOSFET selected matches the voltage and current requirements of the application. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with the latest Analog Devices documentation to ensure availability and correct revision.

Hot Swap Controllers Selection Notes

Select this component when a simple, single-channel hot-swap solution is needed for voltages up to 72V. It is suitable for designs where minimizing external component count is a priority. Consider the adjustable UVLO feature if precise power-good sequencing is required. Ensure the design can accommodate an external P-channel MOSFET, as the controller does not include an internal switch. Evaluate thermal management needs based on the expected load current and duty cycle.

Hot Swap Controllers Part Context

The MAX5903 belongs to the Simple Swapper family from Maxim Integrated, now part of Analog Devices. This series focuses on providing straightforward hot-swap protection for various voltage rails. The MAX5903 specifically targets higher voltage applications compared to lower-voltage counterparts in the lineup. It complements other devices like the MAX5901 and MAX5902, which offer similar functionalities but may differ in voltage ranges or specific feature sets.
