Tiny footprint drop-in solution for life-of-product power backup
Cymbet Corporation announced the availability of the EnerChip CC CBC3105 smart solid state battery. The CBC3105 combines the award winning EnerChip battery with integrated input power conversion, battery management and regulated output capabilities. The Cymbet EnerChip CC is a smart rechargeable solid state battery Uninterruptible Power Supply (UPS in a Chip) that provides power backup to microelectronic devices when main power fails. The EnerChip CC provides power supply monitoring and switches over to the internal solid state backup battery when the supply drops below a set threshold. The EnerChip CC product family can provide anywhere from several hours to several weeks of backup time.
The CBC3105 is an ideal solution for design engineers who need a compact device to back-up 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 CC device family can accomplish all this in a footprint as small as the CBC3105 4mm x 5mm x 0.9mm package that 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.
Features
- Power Manager with Charge Control
- Integrated 5µAh Thin Film Energy Storage
- Built-in Energy Storage Protection
- Temperature Compensated Charge Control
- Adjustable Switchover Voltage
- Charges Integrated EnerChip Over a Wide Supply Range
- Low Standby Power
- SMT - Lead-Free Reflow Tolerant
- Thousands of Recharge Cycles
- Low Self-Discharge
- Eco-Friendly, RoHS Compliant
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 CBC3105 is a 16-pin, 4 mm × 5 mm Dual Flat Nolead (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 backup power to system during exchange of main batteries.
- Consumer appliances that have real-time clocks; provides switchover power from main supply to backup battery
- Energy Harvesting by coupling the EnerChip with energy transducers such as solar panels.
- Embedded Energy where bare die can be embedded into modules or co-packaged with other ICs.
Easy-to-Use Evaluation Kits for Power Backup Applications
Cymbet makes it easy to design EnerChips into new products by offering two EnerChip CC evaluation kits:
- CBC-EVAL-05 EnerChip CC Evaluation Kit which contains everything needed to test EnerChip 12uAh and 50uAh thin film batteries, EnerChip CC CBC3112 and CBC3150 batteries with Integrated Battery Management, and to test multiple batteries in parallel. This kit will also include a CBC3105 evaluation board for experimenting with this device.
- CBC-EVAL-06 Real-Time-Clock Evaluation Kit: includes a Microcrystal NV2123 Real-Time Clock device and a CBC3112 EnerChip CC for battery backup. This kit also includes a Windows based Graphical User Interface to set the clock & test operation in RTC back up and count-down modes.
