The Si3462 from Silicon Labs is a single-port power management controller designed for IEEE 802.3at-compliant Power Sourcing Equipment (PSE). This device operates autonomously, requiring no host processor interface, and supports up to 30 W of maximum output power (Class 4).
Key features include a robust 3-point detection algorithm to prevent false detection events, classification, and PD disconnect capabilities. Intelligent protection circuitry includes input under-voltage lockout (UVLO), classification-based current limiting, and output short-circuit protection. An LED status signal provides port status information.
The Si3462 is pin-programmable to support various power levels and applications, including endpoint and mid-span configurations. It also offers 'no-classify' modes for scenarios where classification steps can be skipped after valid detection, potentially reducing Bill of Materials (BOM) components.
This controller is housed in an 11-Pin Quad Flat No-Lead (QFN) package with a compact 3x3 mm PCB footprint. It is designed for an extended operating temperature range of -40 to +85 °C.
The maximum output power is 30 W (Class 4).
The operating supply voltage is 3.3 V.
The operating temperature range is -40 °C to +85 °C.
It is supplied in an 11-Pin Quad Flat No-Lead (QFN) package with a 3x3 mm PCB footprint.
The standard package quantity is 1500 units.
