Overview
The MCZ34670EGR2 is a Power Over Ethernet (PoE) controller designed for 802.3af compliant applications. It operates as a single-channel device with a switching frequency of 480 kHz and supports a maximum current of 0.7 A. The component is housed in a 20-SOIC package, specifically PDSO20, with a width of 7.50 mm. It functions as a hot swap voltage controller with a power dissipation rating of 800 mW.
Feature Summary
- Integrated PoE controller supporting 802.3af standard
- Hot swap voltage control functionality
- Single channel operation
Applications
- Power over Ethernet endpoint devices
- Network infrastructure equipment requiring 802.3af compliance
- Hot swap power management systems
Procurement Notes
Verify the manufacturer designation, as Freescale Semiconductor was acquired by NXP Semiconductors in December 2015. Ensure the part number matches the specific suffix EGR2 for the correct package and tape-and-reel configuration. Confirm that the component meets the required 802.3af specifications for your application design.
Selection Notes
Select this component for designs requiring integrated PoE detection and classification without external MOSFETs or current-sense resistors. It is suitable for applications needing a compact solution for 802.3af power delivery. Consider the 20-SOIC package constraints and thermal requirements associated with its 800 mW power dissipation rating during PCB layout.
Part Context
This component belongs to the family of PoE controllers originally developed by Freescale Semiconductor. Following the acquisition by NXP Semiconductors, these parts are now managed under the NXP portfolio. The MCZ34670 series provides solutions for powering network devices via Ethernet cables, simplifying system architecture by integrating necessary control logic.
Replacement Considerations
Check for direct equivalents within the NXP semiconductor catalog. Verify pin compatibility and electrical parameters against alternative PoE controllers from other manufacturers if sourcing from non-NXP suppliers.
