PD69108中文资料8-Ports PSE PoE Manager数据手册Microchip规格书

描述 Description

The PD69108 is an eight port, mixed-signal, high-voltage PoE driver. The PoE manager integrates power, analog, and state-of-the-art logic into a single 48-pin, plastic QFN package. The device is used in Ethernet switches and midspans, enabling network devices to share power and data over the same cable. It enables detection of IEEE 802.3at-2009 compliant Type 1 and Type 2 Power Devices (PDs). This ensures safe power feeding and disconnection of ports with full digital control and a minimum of external components.The device executes all real-time functions as specified in the IEEE 802.3af-2003 (AF) and IEEE 802.3at-2009 high power (AT) standards. This includes load detection, AF, and AT classification. In addition, the PD69108 device features Multiple Classification Attempts (MCA) port status monitoring. This provides system-level activities such as power management and MIB support for system management.For new designs, please consider PD69208M / PD69208T4
