The EnerChip™ CBC005 is a solid state, thin film,
rechargeable energy storage device rated at 5µAh at
3.8V. It is ideal as a localized on-board power source
to retain memory or maintain real-time clock function
in mobile systems when main power is interrupted.
The CBC005 is the smallest rechargeable energy
storage device available to Original Equipment
Manufacturers (OEMs) and is a superior alternative to
button and coin cell batteries and super-capacitors in
handheld devices.
Board mounting area of the CBC005 is less than
1/2 the area of a 1210 (3225 metric) surface
mount device and less than 1/4 the thickness.
Such dimensions make the CBC005 ideal for space-
constrained applications.
Because of their solid state design, EnerChip™
energy storage devices are able to withstand solder
reflow temperatures and can be processed in high-
volume manufacturing lines similar to conventional
semiconductor devices. In contrast to traditional
rechargeable batteries and super-capacitors, there
are no harmful gases, liquids or special handling
procedures associated with the EnerChip™.
The CBC005 is based on a patented, all solid state,
rechargeable lithium cell with a nominal 3.8V output.
Recharge is fast and simple with a direct connection
to a 4.1V voltage source and no current limiting
components required. Recharge time is 15 minutes
to 80% capacity. A robust design offers thousands of
charge/discharge cycles. The CBC005 is delivered
as a 1.7mm x 2.25mm x 0.175mm bare die with
two wirebondable pads for co-packaging with other
components or chip-on-board mounting. Die are
shipped in tape-and-reel, waffle packs, and trays.
