QUAD HIGH-VOLTAGE PORT CONTROLLER FOR POE AND

POE+ PSES

Features



Each Si3452/3 high-voltage port

controller supports four PSE power

interfaces

Programmable current limits for PoE

(15.4 W), PoE+ (30 W), and

proprietary systems (up to 40 W) per

port



Programmable architecture supports

IEEE 802.3af (PoE) and IEEE

802.3at (PoE+) PSEs

Programmable current limits for

PoE (350 mA) and PoE+

(600 mA), and custom limits to

850 mA

Per-port current and voltage

monitoring for sophisticated power

management and control

Power policing mode

Robust multi-point detection

Supports 1-Event and 2-Event

classification algorithms

Comprehensive, robust, fault-

protection circuitry

Supply under-voltage lockout

(UVLO)

Output current limit and short-

circuit protection

Foldback current limiting

Dual-threshold thermal overload

protection

Fault source reporting for

intelligent port management

Extended commercial (–10 to 85 °C)

and industrial (–40 to 85 °C)

operating temperatures



I²C interface requires no external

MCU for easy, low-cost management

of 4 to 48 ports by the host system

Unique mixed-signal IC high-voltage

component integration simplifies

design, lowers power dissipation,

minimizes external BOM, and

Ordering Information:

See page 30.



reduces PCB footprint

Internal low-R_ONpower FETs with

Pin Assignments

40-pin QFN

current-sense circuitry

Integrated transient voltage surge

suppressors

DC disconnect (Si3453) or

proprietary dV/dt disconnect

(Si3452) sensing methods

Applications



Power over Ethernet Endpoint

switches and Midspans for IEEE Std

802.3af and 802.3at

Supports high power PDs, such as:

Pan/Tilt/Zoom security cameras

802.11n WAPs



Industrial automation systems

Networked audio

IP Phone Systems and iPBXs

Metropolitan area networked WAPs,

cameras, and sensors

See "9. Pin Descriptions" on page 27.



WiMAX ASN/BTS and CPE/ODU

systems

Multi-band, multi-radio WAPs

Security and RFID systems
