Si3453
Si3453 is QUAD HIGH-VOLTAGE PORT CONTROLLER manufactured by Silicon Labs.
QUAD HIGH-VOLTAGE PORT CONTROLLER FOR POE AND POE+ PSES
Features
- Each Si3453 high-voltage port
- Programmable architecture supports controller supports four PSE power IEEE 802.3af (Po E) and IEEE interfaces
802.3at (Po E+) PSEs
- Programmable current limits for Po E
- Programmable current limits for
(15.4 W), Po E+ (30 W), and
Po E (350 m A) and Po E+ proprietary systems (up to 40 W) per
(600 m A), and custom limits to port 850 m A
- I2C interface requires no external
- Per-port current and voltage
MCU for easy, low-cost management monitoring for sophisticated power of 4 to 48 ports by the host system management and control
- Unique mixed-signal IC high-voltage
- Power policing mode ponent integration simplifies
- Robust multi-point detection design, lowers power dissipation,
- Supports 1-Event and 2-Event minimizes external BOM, and classification algorithms reduces PCB footprint
- prehensive, robust, fault-
