MAX5902AAEUT+T

Hot Swap Controllers Overview

The MAX5902AAEUT+T is a hot-swap voltage controller from the Simple Swapper family, designed for safe insertion of circuit cards into live backplanes. It operates within a supply voltage range of 9V to 72V and features an adjustable current limit. The device provides overcurrent protection with a circuit-breaker function that disables during startup to manage inrush current. It includes thermal limiting and fault timeout features to protect against overheating and persistent faults. Packaged in a compact SOT-23-6 surface-mount case, it supports operation across a temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging by controlling external N-channel MOSFETs without requiring additional external components beyond the switch.
• Provides programmable current limiting and adjustable circuit-breaker thresholds for precise power-supply sequencing and protection.
• Integrates thermal limiting and fault timeout mechanisms to prevent damage from overheating or sustained short circuits.

Hot Swap Controllers Applications

• Network infrastructure equipment
• Telecommunications systems
• Industrial control modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'AA' against official Analog Devices documentation to confirm exact threshold specifications, as variations exist within the MAX5902 series. Confirm package integrity for the SOT-23-6 form factor upon receipt. Ensure compatibility with the target system's voltage rails and MOSFET gate drive requirements before integration.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring robust hot-swap capabilities for positive voltage rails up to 72V. It is suitable for applications needing integrated thermal and electrical protection without complex external circuitry. Consider the SOT-23-6 footprint for space-constrained designs. Verify that the adjustable current limit meets the load requirements and that the operating temperature range aligns with the deployment environment.
