1. General description

New standards and proprietary approaches are enabling Power-over-Ethernet (PoE) systems

capable of delivering up to 90 W to each powered device (PD). Such solutions place increased

demands on the power sourcing equipment (PSE) in terms of “soft-start”, thermal management

and power density requirements. PSMN047-100NSE is designed specifically for high power PoE

applications.

2. Features and benefits

• Enhanced safe operating area (SOA) for superior linear mode operation

• Low RDSon for low I2R conduction losses

• 2 mm x 2 mm space-saving DFN2020 package, 60 smaller than LFPAK33

• Very low IDSS leakage

3. Applications

• High power PoE applications (60 W and higher)

• IEEE802.3at and proprietary PoE solutions

• Fault tolerant load switch - Inrush management and eFuse applications

• Battery management applications
