Si3452
Q UAD H IGH-VOLTAGE P ORT C ONTROLLER
FOR
P OE AND P OE+ PSE S
Features
Applications
Each Si3452 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
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
reduces PCB footprint
Internal low-RON power FETs with
current-sense circuitry
Integrated transient voltage surge
suppressors
Proprietary dV/dt disconnect
sensing methods
Industrial (–40 to 85 °C) operating
temperature
Compact, 6×6 mm2, 40-pin QFN
RoHS-compliant package
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 undervoltage lockout
(UVLO)
Output current limit and short-
circuit protection
Foldback current limiting
Dual-threshold thermal overload
protection
Fault source reporting for
intelligent port management
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
Multi-band, multi-radio WAPs
Security and RFID systems
Industrial automation systems
Networked audio
IP Phone Systems and iPBXs
Metropolitan area networked WAPs,
cameras, and sensors
WiMAX ASN/BTS and CPE/ODU
systems
