Application Scenarios & Design Considerations

1A Dual-Slot PC Card Power Switch w/ Parallel Interface

Alternative Part Number

  • MIC2536-2YM --: Dual-channel current-limited USB power switch with similar enable/fault features, available in SOIC, a functional substitute for the TPS2201 power-distribution switch.
  • LM3526MX-L --: Dual-port USB power switch with current limiting and thermal shutdown, same manufacturer family concept but different series naming, suitable replacement.
  • AAT4616AIGU-1-T1 --: Current-limited high-side power switch with fault flag, comparable voltage/current ratings and function to the original power switch.
