LTC4292规格书详情
DESCRIPTION
The LTC®9101-2A/LTC9102 chipset is a (up to) 48-port power
sourcing equipment (PSE) controller designed for use in IEEE
802.3at Type 1 and 2 compliant Power over Ethernet (PoE) systems.
The LTC9101-2A/LTC9102 is designed to power compliant
802.3af and 802.3at PDs. The LTC9101-2A/LTC9102 chipset delivers
lowest-in-industry heat dissipation using low RDS(ON) external
MOSFETs and 0.1Ω sense resistance per power channel. A transformer-
isolated communication protocol replaces expensive optocouplers
and a complex isolated 3.3V supply, resulting in significant
bill of materials (BOM) cost savings.
Advanced power management features include per-port 14‑bit current/
voltage monitoring, programmable current limits, and versatile
fast shutdown of preselected ports. PD detection uses a proprietary
multipoint detection mechanism, ensuring excellent immunity from
false PD identification. 1-event and 2-event physical classification
are supported. The LTC9101-2A/LTC9102 includes an I2C serial
interface operable up to 1MHz. The LTC9101-2A/LTC9102 is pin or
I2C programmable to negotiate PD-delivered power up to 25.5W.
