1 / 44 page  LTC9101-2/LTC9102 1 Rev. 0 For more information www.analog.com Document Feedback n PoE PSE Switches/Routers and Midspans APPLICATIONS 12/24-Port IEEE 802.3bt PoE PSE Controller The LTC®9101-2 chipset is a 12/24-port power sourcing equipment (PSE) controller designed for use in IEEE 802.3bt Type 3 and 4 compliant Power over Ethernet (PoE) systems. The LTC9101-2/LTC9102 is designed to power compliant 802.3af, 802.3at, and 802.3bt PDs. The LTC9101-2/LTC9102 chipset delivers lowest-in-industry heat dissipation by utiliz- ing low RDS(ON) externalMOSFETsand0.1Ωsenseresistance per power channel. A transformer-isolated communication protocol replaces expensive opto-couplers and complex iso- lated 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. An advanced power management host software layer is available. PD detection uses a proprietary multipoint detec- tion mechanism ensuring excellent immunity from false PD identification. Autoclass and 5-event physical classifica- tion are supported. The LTC9101-2/LTC9102 includes an I2C serial interface operable up to 1MHz. The LTC9101-2/ LTC9102 is pin or I2C programmable to negotiate PD deliv- ered power up to 71.3W. n Fully Compliant IEEE 802.3bt Type 3 and 4 PSE n Up to 24 PSE Ports with Two Power Channels per Port n +80V/–20V Tolerant Port-Facing Pins n ECC-Protected eFlash and Data RAMs n Low Power Path Dissipation per Channel n 100mΩ Sense Resistance n 30mΩ or Lower MOSFET RDS(ON) n Chipset Provides Electrical Isolation n Eliminates Optos and Isolated 3.3V Supply n Very High Reliability Multipoint PD Detection n Connection Check Distinguishes Single- Signature and Dual-Signature PDs n Continuous Per-Port Voltage and Current Monitoring n 1MHz I2C Compatible Serial Control Interface n Pin or I2C Programmable PD Power n Available in a 24-Lead 4mm × 4mm (LTC9101-2) and 64-Lead 7mm × 11mm (LTC9102) QFN Packages All registered trademarks and trademarks are the property of their respective owners.
