World's First Thin-Film Battery with Integrated Battery Management

(Nanowerk News) Cymbet Corporation has developed a breakthrough in battery technology with the introduction of the EnerChip™ CC CBC3112 and CBC3150 thin-film batteries with integrated battery management. The EnerChip CC combines the industry-leading Cymbet EnerChip with sophisticated battery control logic in a single surface mount technology (SMT) package. The EnerChip CC and the EnerChip CC Evaluation Kit will be featured and available for demonstration at the Embedded Systems Conference (ESC) Boston, October 28-29 in Booth 804.
Rechargeable Thin-Film Battery with Battery Management in a Single Package
The EnerChip CC breakthrough is accomplished by internally combining several power system features: thin-film battery, charge pump with integrated DC to DC converter, supply supervisor, low-ripple charger, configurable switchover to battery when input power fails, supply voltage status signals, and operation from 2.5 Volts to 5.5 Volts. The EnerChip CC CBC3112 is a 12™Ah device and the CBC3150 is a 50™Ah device. The EnerChip CC devices are packaged in either 7mm x 7mm or 9mm x 9mm DFN surface mount, reflow tolerant packages
"The EnerChip CC provides significant advantages to our customers. Combining thin-film technology and integrated battery management into a single chip establishes a new benchmark for saving board space and reducing assembly costs", said Bill Priesmeyer, Cymbet CEO. "This is a major step forward for Cymbet as we continue to introduce new innovative energy storage solutions."
A Drop-in Power Solution
The EnerChip CC provides a higher level of integration than previously available. Designers can now utilize one chip instead of a battery, power management IC, and several discrete components. In addition, the EnerChip CC has >5000 recharge cycles, low self-discharge, stable output voltage, and does not require a socket or holder which improves product reliability.
EnerChip CC Enables a Broad Range of Applications
The EnerChip CC is a cost-effective solution in many applications: standby supply for microcontrollers, real-time clocks and SRAMs, wireless sensors and RFID tags, power bridging during exchange of main batteries, and energy harvesting with transducers such as inductive coils and piezoelectric beams. The device is an ideal replacement for supercapacitors and coin cells in applications such as thermostats, hand-held devices, medical diagnostic equipment and embedded computing systems. A single EnerChip CC can manage multiple external EnerChips for high-capacity applications up to 500™Ah. Furthermore, it can power low-voltage systems at 2.5 Volts and 3.3 Volts.
Demonstrating EnerChip CC at ESC Boston 2008
Cymbet will be demonstrating the new EnerChip CC and CBC-EVAL-05 evaluation kit in Booth 804 at the Embedded Systems Conference at the Hynes Convention Center in Boston, October 28-29. Designers can obtain detailed information about the EnerChip CC Evaluation kit at
