Bare die CBC005 suitable for wirebonding. Dimensions: 1.7mm x 2.25mm x 0.175mm. [Not to scale.] The EnerChip™ CBC005 is a solid state, thin film, rechargeable energy storage device rated at 5µAh at 3.8V. It is ideal as a localized on-board power source to retain memory or maintain real-time clock function in mobile systems when main power is interrupted. The CBC005 is the smallest rechargeable energy storage device available to Original Equipment Manufacturers (OEMs) and is a superior alternative to button and coin cell batteries and super-capacitors in handheld devices. Board mounting area of the CBC005 is less than 1/2 the area of a 1210 (3225 metric) surface mount device and less than 1/4 the thickness. Such dimensions make the CBC005 ideal for spaceconstrained applications. Because of their solid state design, EnerChip™ energy storage devices are able to withstand solder reflow temperatures and can be processed in highvolume manufacturing lines similar to conventional semiconductor devices. In contrast to traditional rechargeable batteries and super-capacitors, there are no harmful gases, liquids or special handling procedures associated with the EnerChip™. The CBC005 is based on a patented, all solid state, rechargeable lithium cell with a nominal 3.8V output. Recharge is fast and simple with a direct connection to a 4.1V voltage source and no current limiting components required. Recharge time is 15 minutes to 80% capacity. A robust design offers thousands of charge/discharge cycles. The CBC005 is delivered as a 1.7mm x 2.25mm x 0.175mm bare die with two wirebondable pads for co-packaging with other components or chip-on-board mounting. Die are shipped in tape-and-reel, waffle packs, and trays. ©2012 Cymbet Corporation • Tel: +1-763-633-1780 • www.cymbet.com DS-72-30 Rev02 Page 1 of 3 EnerChip™ CBC005 Energy Storage Device Preliminary Operating Characteristics Parameter Condition Min Typical Max Units Discharge Cutoff Voltage 25°C 3.0 - - V Charge Voltage 25°C 4.0(2) 4.1 4.2 V Non-recoverable - 2.5 - % per year - % per year Self-Discharge (average; 25°C) (1) Recoverable - Operating Temperature - -20 - +70 °C Storage Temperature - -40 - +125 °C Cell Resistance (25°C) Recharge Cycles (to 80% of rated capacity; 4.1V charge voltage) 25°C 40°C Recharge Time (to 80% of rated capacity; 4.1V charge voltage) Discharge Capacity 1.5 (3) (4) KΩ Charge cycle 2 - 7 11 Charge cycle 1000 - 31 48 10% depth-of-discharge 5000 - - cycles 50% depth-of discharge 1000 - - cycles 10% depth-of-discharge 2500 - - cycles 50% depth-of-discharge 500 - - cycles Charge cycle 2 - 11 22 Charge cycle 1000 - 45 70 400nA discharge; 25°C 5.0 - - (1) Failure to cutoff the discharge voltage at 3.0V will result in cell performance degradation.
