EnerChip™ CBC005-BDC

EnerChip 5uAh Bare Die Solid State Battery

The EnerChip is the world’s first solid state thin film battery created on a silicon substrate. The CBC005-BDC can be placed directly on a PCB or inside a packaged part with other integrated circuits. It can be attached using standard wire bonds or solder bumps for flip chip assembly.

During normal operation, the EnerChip bare die is charged from a controlled voltage source. The EnerChip CBC005-BDC can be cycled through >5000 recharge cycles. Designers can take advantage of the fast recharge time of the EnerChip in their designs.

The CBC005-BDC bare die are available in wafers, trays, or tape and-reel for use with automatic insertion equipment.

EnerChip smart solid state batteries are very cost effective.
