Product Overview
LTC9101-1 is a 48-port power sourcing equipment (PSE) controller designed for use in IEEE 802.3at type 2, 802.3bt type 3 and 4 compliant power over ethernet (PoE) systems. It is designed to power compliant 802.3af, 802.3at, and 802.3bt PDs. This device's chipset delivers lowest-in-industry heat dissipation by utilizing low-RDS(ON) external MOSFETs and 0.1 ohm sense resistance per power channel. A transformer-isolated communication protocol replaces expensive opto-couplers and complex isolated 3.3V supply, resulting in significant BOM cost savings. Advanced power management features include per-port 14-bit current/power monitoring, programmable current/ 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 detection mechanism ensuring excellent immunity from false PD identification. It is used in applications such as PoE PSE switches/routers and midspans etc.
- Upto 48 PSE ports with one power channel per port
- Upto 24 PSE ports with two power channels per port
- ECC-protected eflash and data RAMs
- 100Mohm sense resistance, 30Mohm or lower MOSFET RDS(ON)
- Chipset provides electrical isolation, eliminates optos and isolated 3.3V supply
- Very high reliability multipoint PD detection, continuous per-port power and current monitoring
- Connection check distinguishes single signature and dual-signature PDs
- 1MHz I²C compatible serial control interface, pin or I²C programmable PD power
- Undervoltage lock-out is 2.8V typ at (TA = 25°C)
- Operating temperature range from -40°C to 85°C, package style is 24-lead plastic QFN
