9 Revision History

Changes from Revision B (June 2008) to Revision C (January 2024)

  • ドキュメント全体にわたって表、図、相互参照の採番方法を更新Go
  • Updated to new format which does not include specific parameter names and does include min and max columns.  TJ called out in header.  Pin names are used rather than signal names.  BOOT and PH voltages now marked as output voltage.  Footnotes updated and Note 2 removed.  ESD specifications moved to separate table.Go
  • Changed BOOT to PH Absolute Maximum to 6 V maximumGo
  • Deleted Absolute Maximum BOOT to GND maximum voltageGo
  • Added separate ESD tableGo
  • Added CDM ESD rating, Deleted MMGo
  • Added Recommended operating VI input voltageGo
  • Updated Dissipation Ratings table with more detailed Thermal Information tableGo
  • Added condition for typical specifications EC table’s header, added parameter names, and used pin names in parameter descriptions.  Footnote added.Go
  • Changed the following typical specifications in the EC table: IQ(VIN), ISD(VIN), VINUVLO(H), VEN(H), and RDSON(HS).Go
