GOAL: To establish an EFuse to protection the Radio Module from shorts and over current draws

...

• Copy Sensor Modules solution
  • TBD
• TPS2552/TPS2553
  • Adjustable EFuse by TI
    • Fuse limit between 0.075A to 1.7A
    • Vin between 2.5V to 6.5V
    • Typically used in USB charging devices
    • 6 pin, easily to solder package. 
    • Available on JLCPCB
    • Relatively cheap (<$5 per)
      • We can save more money by using a WSON package
  • Differences between the two TPS IC's
    • TPS2552 - Active Enable Low
    • TPS2553 - Active Enable High
