Hot Swap Controllers datasheet and documents for MAX5903ABETT+T

MAX5903ABETT+T

Hot Swap Controllers Overview

The MAX5903ABETT+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 utilizes a single channel architecture. The device is housed in a compact 6-TDFN (3x3 mm) surface-mount package. Key electrical characteristics include a maximum power dissipation of 727 mW and an operating current of 1 mA. It supports an extended industrial temperature range from -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 during startup by gradually turning on the external MOSFET
Provides circuit-breaker functionality for overcurrent protection after startup
Eliminates most external components, requiring only an external P-channel MOSFET

Hot Swap Controllers Applications

Server and storage system backplane power sequencing
Telecommunications equipment hot-swappable modules
Industrial control systems requiring safe board insertion
General-purpose high-voltage hot-swap applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'AB' against official Analog Devices documentation to confirm voltage thresholds and feature sets, as variations exist within the MAX5903 family. Confirm availability status with authorized distributors, as lead times may vary. Ensure the TDFN-6 package compatibility matches your PCB footprint design requirements before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing circuits that require robust hot-swap protection for voltages up to 72V. It is suitable for applications needing minimal external component count while maintaining precise inrush current limiting. Consider the 6-TDFN package size for space-constrained designs. Ensure the external P-channel MOSFET selection aligns with the controller's drive capabilities and thermal requirements.

Hot Swap Controllers Part Context

The MAX5903ABETT+T belongs to the Simple Swapper™ family of hot-swap controllers from Maxim Integrated, now part of Analog Devices. This series focuses on simplifying power management by integrating essential protection features into small packages. The MAX5903 variant specifically targets positive voltage rails, distinguishing it from negative voltage counterparts like the MAX5900.
