1749 - Power Manager II: How do I design a PCB land pattern for Power Manager to meet UL standards?
Designing circuit boards to meet safety certification agency requirements is a very complex subject, and the requirements you need to meet also vary by product and geographical market. For example, two common requirements for PCB design are for for clearance, which is how close two conductors can be separated by air, and creepage, which is how close two conductors may be when sitting on a common substrate. These requirements are set by certifying agencies (UL, TUV) and also vary by voltage carried by the conductors and the application domain.
Requirements may also apply to only some sections of your design and not others. For example,if you are using an ispPAC-POWR1014 to monitor a 48V power rail through a resistive divider, the 48V creepage/clearance requirements may only apply to those components in the divider circuit and not the ispPAC-POWR1014 PCB land pattern. The only way to be certain as to which requirements apply to your product, and how they apply, is to contact the relevant certifying agencies for specific advice.
