Device Overview

Summary

The PoE manager IC integrates power, analog, and state-of-the-art logic into a single 56-pin, plastic QFN package. The device is used in Ethernet switches and midspans to allow network devices to share power and data over the same cable. The PD69204T4 device is a 4-port, mixed-signal, and high-voltage PoE driver. Together with the PD692x0 external MCU, it performs as a PSE system. The PoE controller, PD692x0, is a cost-effective, pre-programmed MCU designed to implement enhanced mode PoE. PD69204T4 supports supply voltages between 32V and 57V without additional power supply sources. A system that powers over four pairs can be implemented by combining two ports of PD69208M, enabling a high-power delivery to compatible PD devices. An on-going monitoring of system parameters for the host software is available via communication. Internal thermal protection is implemented in the chip. PD69204T4 is a low-power dissipation device that uses internal MOSFETs and internal 0.1Ω sense resistors. PD69204T4 is available in a 56 pin, 8 mm x 8 mm QFN package.
