PMICs designed as Power over Ethernet (PoE) controllers facilitate the transmission of electrical power and data over Ethernet cables to powered devices such as IP cameras, VoIP phones, and wireless access points. PoE controllers manage power sourcing equipment (PSE) and powered devices (PD), enabling efficient power delivery and management over Ethernet networks.
