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 back-up power to
system during exchange of main batteries.
• Consumer appliances that have real-time
clocks; provides switchover power from main
supply to backup battery.
• Business and industrial systems such as:
network routers, point-of-sale terminals, single-
board computers, test equipment, multi-function
printers, industrial controllers, and utility meters.
• Energy Harvesting by coupling the EnerChip
with energy transducers such as solar panels.

DFN SMT Package:
The EnerChip CC is the world’s first Intelligent Thin
Film Energy Storage Device. It is an integrated
solution that provides backup energy storage and
power management for systems requiring power
bridging and/or secondary power. A single EnerChip
CC can charge up to 10 additional EnerChips
connected in parallel.
During normal operation, the EnerChip CC charges
itself with a controlled voltage using an internal
charge pump that operates from 2.5V to 5.5V. An
ENABLE pin allows for activation and deactivation
of the charge pump using an external control line
in order to minimize current consumption and take
advantage of the fast recharge time of the EnerChip.
When the primary power supply dips below a user-
defined threshold voltage, the EnerChip CC will signal
this event and route the EnerChip voltage to VOUT.
The EnerChip CC also has energy storage protection
circuitry to enable thousands of recharge cycles.
The CBC3112 is a 20-pin, 7 mm x 7 mm Dual Flat No-
lead (DFN) package, available in tubes, trays, or tape-
and-reel for use with automatic insertion equipment.
