DESCRIPTION
The LTC?9101-2B/LTC9102 chipset is a 12-/24-/48-port power
sourcing equipment (PSE) controller designed for use in IEEE
802.3bt-compliant Type 3 2-pair Power over Ethernet (PoE) systems.
The LTC9101-2B/LTC9102 is designed to power compliant
802.3af, 802.3at, and 802.3bt PDs. The LTC9101-2B/LTC9102
chipset delivers lowest-in-industry heat dissipation by utilizing low
RDS(ON) external MOSFETs and 0.1Ω sense resistance per power
channel. A transformer-isolated communication protocol replaces
expensive opto-couplers and a complex isolated 3.3V supply, resulting
in significant BOM cost savings.
Advanced power management features include per-port 14?bit current/
voltage monitoring, programmable power limits, and versatile
fast shut down of preselected ports. PD detection uses a proprietary
multipoint detection mechanism ensuring excellent immunity
from false PD identification. Autoclass and 2-event physical classification
are supported. The LTC9101-2B/LTC9102 includes an I2C
serial interface operable up to 1MHz. The LTC9101-2B/LTC9102
is pin or I2C programmable to negotiate PD delivered power up to
25.5W.
