EnerChip™ Smart Solid State Batteries
Cymbet EnerChip battery and energy harvesting solutions provide an innovative way to place energy storage where it has never gone before. EnerChip bare die can be embedded with other integrated circuits and packaged parts use standard automated SMT and reflow solder assembly.
EnerChips are very cost effective and are priced as low as $0.20 for CBC005 bare die or $0.50 for CBC3105 packaged parts in high volumes. Click here to get a quote and learn more....
is a 5uAh (Lifecycle Capacity = 2.5mAh) rechargeable 1.75mm x 2.15mm x 200 microns thick solid state battery bare die to be co-packaged with other integrated circuits in a single package or multi-chip module. The electrical specifications for the CBC005-BDC are contained in the CBC3105 datasheet as linked below.
is a 1uAh (Lifecycle Capacity = .5mAh) rechargeable 1.375mm x0.85mm x 200 microns thick solid state battery bare die to be co-packaged with other integrated circuits in a single package or multi-chip module.
EnerChip CBC910 Power Management and Charge Control ASIC
is a complete single chip power management solution that provides battery backup control and power management for systems requiring power bridging and/or secondary power. The CBC910 is integrated in the EnerChip CC 31XX product family, but is also available as a seperate device in an 8 pin DFN package or a bare die. The bare die CBC910 is particularly useful for projects using EnerChip solid state battery bare die.
Using EnerChip Lifecycle Capacity Specifications for Power Budget Calculations
When evaluating EnerChip Solid State Batteries for your designs, it is important to review the Lifecycle Capacity (LC) of each device. Since EnerChips can be charge cycled many thousands of times, an EnerChip has a similar energy storage equivalency per volume of much larger primary coin cell batteries. For example, the 50uAh EnerChip CBC3150 is rechargeable 5000 times at a 10% depth of discharge to 80% of rated capacity. This yields a Lifecycle Capacity of 25mAh using the conservative datasheet charge cycle specifications for this device. Therefore, the 10x smaller footprint EnerChip has the same Lifecycle Capacity per unit volume of a much larger problematic primary coin cell battery.
A very good overview of the EnerChip specifications and capabilities can be found in the Circuit Cellar article "LiON King - A Look at "Battery-in-a-Chip" Technology.
The EnerChip is an Eco-friendly device, providing long intervals of operation between recharges. When coupled with energy harvesting techniques, these devices can provide the energy storage to build self-contained, long lived powered systems that have minimal negative environmental impact. As a solid-state device, the EnerChip is RoHS compliant and contains no hazardous materials, flammable solvents or liquids that can harm the user or the environment, therefore eliminating or reducing end-of-life product costs. Environmental friendliness is a key EnerChip attribute, since the product is designed to eliminate battery replacement and last the life of the product it powers.

All members of the EnerChip family are reflow tolerant and are available in Tape and Reel for use with high-speed SMT pick & place assembly processes. The devices offer a fast recharge time ( 20 minutes to 80%), and are capable of greater than 5000 charge/discharge cycles. EnerChips do not suffer from the self-discharge limitations associated with super capacitors or shelf life limitations common to chemical batteries.
To facilitate easy evaluation of the EnerChip rechargeable battery products, Evaluation Kits have been created that provide everything a designer needs to fully evaluate the performance and operation of the EnerChip energy storage devices.
