Hot Swap Controllers datasheet and documents for MAX5921BESA+T

MAX5921BESA+T

Hot Swap Controllers Overview

The MAX5921BESA+T is a -48V hot-swap controller designed for safe insertion and removal of circuit boards in live backplane systems. It integrates an N-channel MOSFET driver with external current sensing via an RSENSE resistor. The device provides programmable soft-start, adjustable current limit, and overvoltage protection. It operates within a supply voltage range of 3V to 60V and supports continuous drain currents up to 10A depending on the external MOSFET selection.

Hot Swap Controllers Feature Summary

Integrates high gate pulldown current capability for rapid MOSFET turn-off during fault conditions
Supports external RSENSE configuration for precise current limiting and power monitoring
Provides programmable soft-start to control inrush current during board insertion
Includes overvoltage protection with hysteresis to prevent damage from input transients

Hot Swap Controllers Applications

Telecommunications equipment requiring hot-swappable modules
Industrial control systems with -48V DC power distribution
Networking hardware such as routers and switches
Server backplanes supporting live board replacement

Hot Swap Controllers Procurement Notes

Verify the exact suffix 'ESAT' corresponds to the tape-and-reel packaging variant. Confirm RoHS compliance status through official Analog Devices documentation, as older Maxim parts may have leaded options. Ensure the ordering part number matches the specific temperature grade and package style required for your design.

Hot Swap Controllers Selection Notes

Select this component when designing -48V systems requiring controlled power-up sequences. Evaluate the external MOSFET's RDS(on) and thermal characteristics against the expected load current. Consider the external RSENSE value for setting the desired current limit threshold. Verify that the SOIC-8 package fits the PCB layout constraints.

Hot Swap Controllers Part Context

This part belongs to the MAX5921 family of hot-swap controllers from Maxim Integrated, now part of Analog Devices. These devices are widely used in telecom and industrial applications where system availability depends on the ability to replace faulty boards without shutting down the entire system. The MAX5921 series offers various pinouts and features to suit different voltage and current requirements.
