Status: In Production
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.
The PD-IM-7604-4T4H evaluation board is developed based on PD69208T4, PD69204T4 and PD69200 chipsets, and demonstrates the operation of four 4-pair ports and four 2-pair ports systems. The evaluation system provides designers with the required environment to evaluate the performance and implementation of PD69204T4 (four ports) and PD69208T4 (eight ports) PoE managers and PD69200 PoE...
