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
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
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.
