Product Overview

The LT4275BIMS#PBF is a pin-for-pin compatible family of IEEE 802.3 and LTPoE++ Powered Device (PD) Controller employs a proprietary LTPoE++ classification scheme. The LT4275A is fully compatible with IEEE 802.3. The LT4275B is an IEEE 802.3 at compliant, Type 2 (PoE+) PD delivering up to 25.5W. The LT4275 internal charge pump provides an N-channel MOSFET solution, eliminating a larger and more costly P-channel MOSFET. A low RDS(ON) MOSFET also maximizes power delivery and efficiency, reduces power and heat dissipation and eases thermal design. Startup inrush current is adjustable with an external capacitor. The LT4275 also includes a power good output, on-board signature resistor, undervoltage lockout and thermal protection. It drives a single opto-coupler to indicate the power level of the attached PSE. Pin-selectable support for non-standard low voltage operation is provided.
  • Overtemperature protection
  • Integrated signature resistor
  • External Hot Swap™ N-channel MOSFET for lowest power dissipation and highest system efficiency
  • Programmable aux power support as low as 9V
  • Optional support of non-standard low voltage PoE
