APPLICATION NOTE 405
Power-Fault Protection Layout
Abstract: This application note discusses how to modify the PCB layout for either of two scenarios for second level GR-1089/UL
60950: fuse opens quickly, or fuse doesn't open at all. A thermal plane is added to dissipate heat for the case where a technical
should not be dispatched to replace a fuse.
