EnerChip™ CBC50-BDC

Rechargeable Solid State Battery Bare Die

The EnerChip is the world’s first solid state thin film battery created on a silicon substrate. The CBC050-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 CBC050-BDC can be cycled through >5000 recharge cycles. Designers can take advantage of the fast recharge time of the EnerChip in their designs.

The CBC050-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.
