Cymbet Releases Thin-Film Battery With Integrated Battery Management
Cymbet Corp. has developed what it describes as 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 Cymbet EnerChip with what is described as sophisticated battery control logic in a single surface mount technology (SMT) package.
The EnerChip CC internally combines several power system features: thin-film battery, charge pump with integrated dc-dc converter, supply supervisor, low-ripple charger, configurable switchover to battery when input power fails, supply voltage status signals, and operation from 2.5 to 5.5V. The EnerChip CC CBC3112 is a 12µAh device and the CBC3150 is a 50µAh device. The EnerChip CC devices are packaged in either 7 x 7mm or 9 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."
According to the company, 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.
The EnerChip CC is described as 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 a suitable 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 500µAh. It can also power low-voltage systems at 2.5 and 3.3V.
