MAX5992AETG+

Overview

The MAX5992AETG+ is a Power Management IC (PMIC) classified as an Ethernet over Power (PoE) controller manufactured by Analog Devices Inc./Maxim Integrated. It functions as a single-channel PD (Powered Device) controller compliant with IEEE 802.3af and 802.3at standards. The device operates within a supply voltage range of up to 60V and draws a supply current of 1.5mA. Designed for surface mount installation, it utilizes a 24-TQFN package with dimensions of 4x4 mm. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports dual standard compliance for both 802.3af and 802.3at PoE protocols
• Integrates internal switching capability for efficient power delivery
• Includes auxiliary functionality for enhanced system control

Applications

• Ethernet powered devices requiring multi-source input support
• High-performance network equipment interfaces
• Professional power management systems

Procurement Notes

Verify availability status carefully as the part may be discontinued or subject to limited supply constraints. Confirm RoHS3 compliance and REACH status prior to integration. Check for specific ordering suffixes that may alter packaging or function. Ensure the source document explicitly identifies this exact part number to avoid substitution errors.

Selection Notes

Select this component for applications requiring strict adherence to IEEE 802.3af/at standards in a compact form factor. The 24-TQFN package suits space-constrained designs. Verify thermal performance requirements against the specified operating temperature range. Consider the internal switch feature when designing the power path to minimize external component count.

Part Context

This component belongs to the MAX5992 series of specialized power management ICs. It is designed specifically for Ethernet over Power applications, distinguishing itself from general-purpose PMICs by its protocol-specific control logic. The manufacturer provides dedicated datasheets and EDA models to support design implementation.
