MP8003AGQ-Z

Overview

The MP8003AGQ-Z is a Power over Ethernet (PoE) controller designed for Powered Devices (PD) compliant with IEEE 802.3af and 802.3at standards. It operates within a supply voltage range of 0V to 57V and supports a maximum power output of 25.5W. The device features an auxiliary control function and lacks an internal switch, requiring external components for power switching. It is housed in a 10-QFN (3x3mm) package with exposed pad for surface mount installation.

Feature Summary

Supports IEEE 802.3af and 802.3at PoE standards for Powered Device applications
Includes auxiliary control functionality for enhanced interface management
Operates without an integrated internal power switch

Applications

IEEE 802.3af PoE Powered Device implementations
IEEE 802.3at PoE+ Powered Device implementations
Network interface circuits requiring PoE control

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct packaging configuration. Confirm that the selected variant matches the required RoHS compliance status and moisture sensitivity level for your assembly process. Cross-reference the datasheet to validate pinout compatibility and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when designing a Powered Device that requires strict adherence to IEEE 802.3af/at protocols. The absence of an internal switch necessitates the integration of external power switches, which allows for flexible current handling capabilities beyond the controller's limits. Ensure the design accommodates the 0V to 57V operating range and utilizes the 10-QFN package constraints.

Part Context

This part belongs to the MP8003 series of PoE controllers manufactured by Monolithic Power Systems. It serves as a specialized interface solution for network equipment, distinguishing itself from integrated PoE switches by focusing solely on the Powered Device side of the communication link. The QFN package facilitates compact PCB layouts for modern networking hardware.
