BCM59011B0KMLG Overview
A Power over Ethernet PSE controller is a power management IC that sits in the powered device port of network switches and midspans. It negotiates power with the connected powered device (PD), classifies the load, monitors current and voltage, and disconnects faulty ports - forming the power-delivery layer of the power management IC hierarchy alongside regulators and battery management ICs.
Key features include its 30 W+ power-per-port capability, which supports higher-power PoE classes used in access points, IP cameras, and industrial endpoints, and its octal-port system-level designation (PSE 30W+ OCTAL POE), indicating deployment in multi-port PoE switching infrastructure where eight channels are managed as a group. According to Octopart's parameter comparison, the device is categorized as Type: Controller (PSE), Number of Channels: 1, Power - Max: 30 W, and Internal Switch(s): No, meaning an external MOSFET switch stage is required in the power path.
Because the internal switch is not integrated, designers pair the BCM59011B0KMLG with external pass devices and sense resistors, which gives flexibility in thermal design but adds board area. The single-channel controller architecture is typically replicated across the ports of an octal system, sharing supervisory and sequencing logic.
Typical applications include enterprise PoE switch line cards, PoE midspan injectors, wireless access point infrastructure, and surveillance camera power distribution where 30 W-class power negotiation and fault isolation are required.
A key design consideration is the external switch selection: the external MOSFET must handle the 30 W-class current with adequate RDS(on) and SOA margin, and current-sense accuracy directly affects PoE classification compliance.
