The EnerChip CC CBC3105 smart solid-state battery combines the EnerChip battery with integrated input power conversion, battery management and regulated output capabilities. The smart battery is essentially an uninterruptible power supply (UPS) in a chip that provides power backup to microelectronic devices when main power fails. It provides power supply monitoring and switches over to the internal solid-state backup battery when the supply drops below a set threshold for anywhere from several hours to several weeks of backup time, all from a tiny package with a footprint as small as 4 by 5 by 0.9 mm. It is an ideal back-up for a real time clock or microcontroller during power failure where coin cell batteries or super caps will not work due to size, reliability, no battery doors, no battery replacement, battery disposal issues, or need for life-of-product power. The CBC3105 uses surface mount/reflow solder assembly and is RoHS tested-compliant. The EnerChip CBC3105 is priced as low as $0.50 in high volumes. The EnerChip CC CBC3112 and CBC3150 provide even more energy storage in similar small footprint packages. Evaluation kits are available: The CBC-EVAL-05 kit contains everything needed to test EnerChip 12-µAh and 50-µAh thin-film batteries, the EnerChip CC CBC3112 and CBC3150 batteries with integrated battery management, and multiple batteries in parallel. This kit will also include a CBC3105 evaluation board for experimenting with this device. The other evaluation kit is the CBC-EVAL-06 real-time-clock evaluation kit. It contains a Microcrystal NV2123 real-time clock and a CBC3112 EnerChip CC for battery backup. It also includes a Windows based graphical user interface to set the clock and test operation in real-time-clock back-up and count-down modes.
