DESCRIPTION
The LTC®9101-3/LTC9103 chipset is a 8/16-port power
sourcing equipment (PSE) controller and power manager
designed for use in IEEE 802.3at compliant Power
over Ethernet (PoE) systems. The LTC9101-3 manages a
user-defined system-level power budget across all ports.
Port power is automatically assigned based on system
power availability, initial physical classification and after
power up, port dynamic power consumption.
The LTC9101-3 prioritizes port power by port number (port 1
is highest priority) and automatically removes power from
lower priority ports to accommodate higher priority ports.
The LTC9101-3 features an interface to control an external
serial LED driver. LED indications include Port On, Port
Off, Port Power Denied, and Port Fault states. A Supply
Overload LED indicates system power usage is near
power limit or a port is being denied power.
The LTC9101-3 operates without a host present.
Configuration is accomplished by pin settings and I2Cbased
flash programming.
The LTC9101-3 autonomously performs compliant
802.3at detection, classification power up, power on, and
fault management.
