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.
