Applications

EnerChips are an attractive RTC backup alternative to batteries or supercapacitors, especially when the finished product has limited PCB space, size constraints or needs to be sealed or installed in a hard-to- reach location. They are also excellent if you have any of these design requirements:

  • Battery must be RoHS and WEEE compliant
  • Product can be discarded without removing battery
  • Product must have battery installed during shipping via air
  • Battery must be rechargeable to support a lifetime of power outages
  • Battery must provide backup power for several hours during a main power failure Advantages of Combining These Two Parts Cymbet EnerChips are solid-state, rechargeable batteries with the following characteristics when compared to conventional rechargeable batteries:
  • Low self-discharge
  • Are solder reflow tolerant
  • Flat discharge voltage profile
  • High charge/discharge cycle life
  • Simple voltage controlled charging
  • Have no flammable solvents to leak or catch fire
  • Are offered in low profile surface mount packages Ambiq AM1803 Real Time Clock How2 Info Sheet Ambiq AM1803 RTC Power Backup with EnerChip™ Battery AM1803 CBC3105 CBC3112 CBC3150 Iq (nA at 3V) Back up time (hrs) Package Size (mm x mm) Back up time (hrs) Package Size (mm x mm) Back up time (hrs) Package Size (mm x mm) XXX XXX 4 x 5 XXX 7 x 7 XXX 9 x 9 Documentation
