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.
