Si3473B-IM规格书详情
描述 Description
The Si3473B-IM IEEE 802.3bt compliant PoE PSE Controller provides up to 45 W of power for eight 2-pair Ethernet ports in a QFN56 package. The Si3473B-IM automatically detects valid Powered Devices (PDs), monitors for fault conditions, and cuts off port power when connected PDs are removed. Each port’s supply voltage and current are measured and monitored in real-time and may be accessed via the I²C interface, enabling sophisticated system-level power management and control. Fully autonomous operation is also supported. Uses 200 mΩ sense resistor for improved thermal performance.
