MAX5903NNEUT+T

Hot Swap Controllers Overview

The MAX5903NNEUT+T is a hot-swap controller from the Simple Swapper series, designed for safe insertion of circuit cards into live backplanes. It operates within a supply voltage range of +9V to +72V and features a single channel with no internal switch. The device provides inrush current limiting and overcurrent protection via a circuit-breaker function. Key specifications include a supply current of 1 mA, an operating temperature range of -40°C to +85°C, and a SOT-23-6 surface-mount package.

Hot Swap Controllers Feature Summary

• Eliminates external components except the p-channel MOSFET for simplified hot-swap implementation
• Limits inrush current to prevent power-supply rail glitches during card insertion
• Provides adjustable under-voltage lockout (UVLO) for programmable startup sequencing
• Includes thermal limiting and fault timeout features for robust system protection

Hot Swap Controllers Applications

• Hot-plugging circuit cards into live backplanes
• Power-supply sequencing in server systems
• Adjustable circuit breaker applications
• Network equipment power management

Hot Swap Controllers Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct packaging and temperature grade. Confirm that the '+T' designation aligns with the required reel quantity and tape-and-reel specifications. Cross-reference the manufacturer's latest datasheet revision to validate RoHS compliance and lead-free status before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when a single-channel hot-swap solution is required for voltages up to 72V. It is suitable for designs prioritizing minimal external component count and integrated thermal protection. Ensure the application requires an external p-channel MOSFET for the switching element. Consider the SOT-23-6 package constraints for PCB layout and thermal dissipation requirements.

Hot Swap Controllers Part Context

This device belongs to the MAX5902/MAX5903 family of Simple Swapper hot-swap controllers. These devices are engineered to allow safe hot-plugging without causing glitches on the power-supply rail. The family offers a simple solution by eliminating most external components, focusing on inrush current limiting and circuit-breaker functionality for overcurrent protection.
