LTspice: SOAtherm Tutorial

Dan Eddleman - Senior Applications Engineer Oct 8th 2014
Verifying that a Hot Swap design does not exceed the capabilities of a MOSFET is a challenge at high power levels. Fortunately, thermal behavior and SOA may be modeled in circuit simulators such as LTspice IV® . The SOAtherm-NMOS symbol included in LTspice contains a collection of MOSFET thermal models developed by Linear ...

LTspice: Modeling Safe Operating Area Behavior of N-channel MOSFETs

Dan Eddleman - Senior Applications Engineer
Gabino Alonso - Strategic Marketing Engineer Aug 22nd 2014
Introduction Often the most challenging aspect of Hot Swap™ circuit design is verifying that a MOSFET’s Safe Operating Area (SOA) is not exceeded. The SOAtherm tool distributed with LTspice IV® simplifies this task, allowing a circuit designer to immediately evaluate the SOA requirements of an application and ...
