  • Wide operating voltage range: 2.8 V to 5.5 V
  • Adjustable current limit (0.63 A to 2 A for TPS2115A)
  • Reverse and cross-conduction blocking
  • Low standby current (0.5 μA typical) and low operating current (55 μA typical)
  • Switch status output
  • Automatic and manual switching modes
  • Available in TSSOP-8 and SON-8 packages

Applications

  • Personal Computers (PCs)
  • Personal Digital Assistants (PDAs)
  • Digital Cameras
  • Modems
  • Cell Phones
  • Digital Radios
  • MP3 Players
  • Other portable electronic devices requiring dual power sources

The TPS2115ADRBTG4 is particularly useful in systems where there is a need to switch between two power supplies, ensuring that the system remains operational even if one power source fails or is removed.
