Si3474B-IM

Multi-Port PSE Controllers

The Si3474B-IM IEEE 802.3bt compliant PoE PSE Controller provides up to 90 W of power per Ethernet port in a QFN56 package. The Si3474B-IM automatically detects valid Powered Devices (PDs), monitors for fault conditions, and cuts off port power when connected PDs are 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.
