During normal operation, the CBC910 delivers a controlled voltage using an internal charge pump that operates from 1.5 V to 5.5 V. An ENABLE pin allows for activation and deactivation of the charge pump using an external control line in order to minimize current consumption when battery charge current is not needed. When the primary power supply dips below a user- defined threshold voltage, the CBC910 will signal this event and route the battery voltage to VOUT. The CBC910 also has battery protection circuitry to protect an attached battery from being discharged too deeply. The CBC910 is available in an 8-pin VDFN package and as a bare die having 9 bond pads. Preliminary Applications • Standby supply for non-volatile SRAM, Real-time clocks, controllers, supply supervisors, and other system-critical components. • Wireless sensors and RFID tags and other powered, low duty cycle applications. • Localized power source to keep microcontrollers and other devices alert in standby mode. • Power bridging to provide back-up power to system during exchange of main batteries. • Consumer appliances that have real-time clocks; provides switchover power from main supply to backup battery. • Business and industrial systems such as: network routers, point-of-sale terminals, single- board computers, test equipment, multi-function printers, industrial controllers, and utility meters. • Energy Harvesting by coupling the energy storage device with energy transducers such as solar panels.
