DC2642A-A shows the LTC4041 supercapacitor backup power manager operating with a stack of two series supercapacitor. The board demonstrates the design of a 5V rail with a short-term power backup using 10F supercapacitors.
The input current limit, charge current limit, charge voltage, power fail threshold, and boost voltage are all configurable through changing resistor values on the board. Test points for all monitoring pins and LED indicators on status pins are also available to assist in the evaluation.
