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

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.

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.
