Hot Swap Controllers datasheet and documents for MAX5903ABETT+
Hot Swap Controllers Overview
The MAX5903ABETT+ 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 TDFN-6 package. The device limits inrush current during startup and provides overcurrent protection via a circuit-breaker function that activates after the MOSFET has fully turned on. It requires only an external P-channel MOSFET, eliminating other passive components.
Hot Swap Controllers Feature Summary
- Enables safe hot-plugging into live backplanes without causing power-supply glitches
- Limits inrush current by gradually turning on the external P-channel MOSFET
- Provides circuit-breaker overcurrent protection after startup phase
- Requires minimal external components, needing only one 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 'ABETT' against official Analog Devices documentation to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer datasheets. Check current availability as distribution 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 systems requiring simple hot-swap functionality for voltages up to 72V. It is suitable for applications needing precise inrush current limiting and robust overcurrent protection without complex external circuitry. Consider the TDFN-6 package constraints for thermal management and PCB layout requirements.
Hot Swap Controllers Part Context
Part of the Simple Swapper family from Maxim Integrated, now part of Analog Devices. This series focuses on simplifying hot-swap designs by integrating control logic with minimal external component requirements. The MAX5903 variant specifically targets positive voltage rails up to 72V.
Hot Swap Controllers FAQ
What external component is required for operation?
Only an external P-channel MOSFET is required; all other control components are integrated.
How does the device handle overcurrent conditions?
It provides a circuit-breaker function that activates after the startup phase to limit inrush current and protect against faults.
