Product Overview
LTC®4266 is a quad PSE controller designed for use in IEEE 802.3 Type 1 and Type 2 (high power) compliant Power over Ethernet systems. External power MOSFETs enhance system reliability and minimize channel resistance, cutting power dissipation and eliminating the need for heatsinks even at Type 2 power levels. External power components also allow use at very high power levels while remaining otherwise compatible with the IEEE standard. 80V-rated port pins provide robust protection against external faults. Application includes high power PSE switches/routers, high power PSE midspans.
- Four independent PSE channels
- High capacitance legacy device detection
- Midspan backoff timer
- Supports proprietary power levels above 25W
- Main PoE supply voltage range from 45 to 57V (for IEEE type 1 complaint output, TA = 25°C)
- Classification voltage range from 16 to 20.5V (AGND – VOUTn, 0mA ≤ ICLASS ≤ 50mA, TA = 25°C)
- 36-lead plastic wide SSOP package
- Temperature rating range from -40°C to 85°C
