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 PD39208 device is an 8-port, mixed-signal, and high-voltage PoE driver. Together with the PD39210 external MCU, it performs as a PSE system designed specifically to support the IEEE 802.3at standard. The PD39208 supports supply voltages between 32V and 57V without additional power supply sources. An on-going monitoring of system parameters for the host software is available via system communication. Internal thermal protection is implemented in the chip. PD39208 is a low-power dissipation device that uses internal MOSFETs and internal 100 mΩ sense resistors. PD39208 is available in a 56 pin, 8 mm x 8 mm QFN package.
