Overview
The MAX5972BETE+ is a hot-swap voltage controller designed for IEEE 802.3af/at-compliant powered devices. It operates within a supply voltage range of 4V to 60V and supports dual-channel configurations. The device integrates programmable current limit, overvoltage protection, and undervoltage lockout features. It utilizes a TQFN-16 package with an exposed pad for thermal management. The component functions as a power switch controller, managing inrush current and providing fault protection for downstream circuitry in network applications.
Feature Summary
- Compliance with IEEE 802.3af/at standards for powered device implementation
- Integrated dual-channel hot-swap control with programmable thresholds
- Built-in protection mechanisms including overvoltage and undervoltage lockout
Applications
- IEEE 802.3af/at compliant powered network equipment
- Hot-swap power distribution modules
- Voltage regulation for peripheral interface circuits
Procurement Notes
Verify the exact suffix and marking on physical components to confirm authenticity. Check manufacturer documentation for current lifecycle status, as availability may be restricted. Ensure compatibility with system voltage requirements before integration. Confirm RoHS compliance details through official datasheets.
Selection Notes
Select this component for applications requiring strict adherence to IEEE 802.3af/at powered device specifications. Evaluate thermal performance due to the TQFN-16 package constraints. Consider the dual-channel capability if multiple power rails require synchronized control or independent fault management within the same footprint.
Part Context
This part belongs to the Maxim Integrated hot-swap controller family, specifically tailored for Ethernet-powered applications. It addresses the need for reliable power sequencing and protection in compact network infrastructure devices. The design supports robust operation in environments subject to frequent connection and disconnection events.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when considering generic replacements.
