The EnerChip CC is the world’s first Intelligent Thin Film Battery. It is an integrated solution that provides battery backup and power management for systems requiring power bridging and/or secondary power. A single EnerChip CC can charge up to 10 additional EnerChips connected in parallel. Two EnerChip CC devices are on the EVAL-05, a CBC3112 and a CBC3150, with battery capacities of 12 μAh and 50 μAh, respectively. The CBC-EVAL-05 evaluation board utilizes a 24-pin DIP format that mates with a 24-pin DIP socket on a target board.
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 the designer to activate and deactivate 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 battery voltage to VOUT. The EnerChip CC also has battery protection circuitry to enable thousands of recharge cycles. The CBC3112 and CBC3150 data sheets contain complete specifications and application circuits.
