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.

Applications

• Standby supply

for non-volatile SRAM, real-time

clocks, controllers, supply supervisors, and other

system-critical components.

• Portable devices

requiring ultra-slim profile and

small footprint backup power source.

• Localized power source

to keep microcontrollers

and other devices alert in standby mode.

• Power bridging

to provide backup power to

system during exchange of main battery.

Bare die CBC005 suitable for wirebonding.

Dimensions: 1.7mm x 2.25mm x 0.175mm.
