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. PSMN071-100NSE is designed specifically for low 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 footprint than LFPAK33
• Very low IDSS leakage
3. Applications
• PoE applications (<60 W)
• IEEE802.3at and proprietary PoE solutions
• Fault tolerant load switch - inrush management and eFuse applications
• Battery management applications
