Broadcom offers the most advanced Power over Ethernet Power Sourcing Equipment (PoE PSE) solutions with highest integration, lowest power consumption, highest reliability, and greatest flexibility, resulting in lowest overall system cost. With better thermal properties, integrated Field-Effect Transistor (FETs), and current-sense mechanism, many of the external components that are required on other systems are eliminated, saving both BOM costs as well as PCB board space. Since Broadcom PoE PSE is already certified by Underwriters Laboratory (UL), end products can be UL certified without going through testing. Integrated MCU provides the flexibility to perform field upgrade through firmware download for custom features and bug fixes.
