LTC9101AUF-3#TRPBF DESCRIPTION

LTC9101AUF-3#TRPBF APPLICATIONS

The LTC®9101-3/LTC9103 chipset is a 8/16-port powersourcing equipment (PSE) controller and power man-ager designed for use in IEEE 802.3at compliant Powerover Ethernet (PoE) systems. The LTC9101-3 manages auser-defined system-level power budget across all ports.Port power is automatically assigned based on systempower availability, initial physical classification and afterpower up, port dynamic power consumption.The LTC9101-3 prioritizes port power by port number (port 1is highest priority) and automatically removes power fromlower priority ports to accommodate higher priority ports.The LTC9101-3 features an interface to control an externalserial LED driver. LED indications include Port On, PortOff, Port Power Denied, and Port Fault states. A SupplyOverload LED indicates system power usage is nearpower limit or a port is being denied power.The LTC9101-3 operates without a host present.Configuration is accomplished by pin settings and I2C-based flash programming.The LTC9101-3 autonomously performs compliant802.3at detection, classification power up, power on, andfault management.
