A complete supercapacitor back-up power management system for 2.9 to 5.5V supply rails is available from Analog Devices. The LTC4041 uses an on-chip bi-directional synchronous converter to provide high efficiency step-down supercapacitor charging. There is also high current, high efficiency boost back-up power. When external power is available, the device operates as a step-down battery

This design is a type of indicator that is used in voltage reading. It operates as an indicator rather than a meter that drives LED for voltage indication. Voltage thresholds are 1.5, 3, 4.5 and 6V. Above each incremental threshold an additional LED turns on. Many voltage indicators rely upon the measurement source voltage for
