Design considerations
System capability must include ‘soft-start’ procedures, resilience to short-circuits, together with optimized thermal management and power density.
Superior protection and performance, such as low RDS(on) parameters, can be achieved by using dedicated PoE MOSFETs. They are designed specifically for the latest high-power PSE controllers.
MOSFET and GaN FET Handbook
Drawing on over 20 years’ of experience, the MOSFET and GaN FET Application Handbook: A Power Design Engineer’s Guide brings together a comprehensive set of learning and reference materials relating to the use of MOSFETs and GaN FETs in real world systems.
Nexperia in action
PSMN075-100MSE, PSMN040-100MSE, PSMN4R8-100BSE MOSFETs referenced in Linear Technology's LTC4279 New PSE Controller datasheet are from our differentiated ASFETs for Hotswap and Soft Start / ASFETs for Power over Ethernet portfolios.
