The EnerChip™ CBC050 is a surface-mount, solid

state, rechargeable energy storage device rated

for 50µAh at 3.8V. It is ideal as a localized, on-

board power source for SRAMs, real-time clocks

and microcontrollers which require standby power

to retain time or data. It is also suitable for RFID

tags, smart sensors, and remote applications

which require a miniature, low-cost, and rugged

power source. For many applications, the CBC050

is a superior alternative to coin cell batteries and

supercapacitors.

Because of their solid state design, EnerChip™

storage devices are able to withstand solder reflow

temperatures and can be processed in high-

volume manufacturing lines similar to conventional

semiconductor devices. There are no harmful gases,

liquids or special handling procedures, in contrast to

traditional rechargeable batteries.

The EnerChip recharge is fast and simple, with a

direct connection to a 4.1V voltage source and

no current limiting components. Recharge time is

20 minutes to 80% capacity. Robust design offers

thousands of charge/discharge cycles. The CBC050

is packaged in an 8 mm x 8 mm quad flat package. It

is available in reels for use with automatic insertion

equipment.

Applications

Standby supply

•

for non-volatile SRAM, real-time

clocks, controllers, supply supervisors, and other

system-critical components.

Wireless sensors and RFID tags

•

and other

powered, low duty cycle applications.

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 batteries.

Energy Harvesting

•

by coupling the EnerChip

with energy transducers such as solar panels.

Embedded Energy

•

where bare die can be

embedded into modules or co-packaged with

other ICs.
