The LS0502SCD33 is a complete solution for system with backup storage capacitor or capacitor bank. It integrated input overvoltage, overcurrent protection circuit, a reverse blocking switch and super capacitor charging control circuit. It also has built-in cell balance to provide protection over two cell super capacitor system. When the main supply is present and above the minimum system supply voltage, system will draw power from input supply. At the same time, integrated linear charger charges the storage element at up to 300 mA current. Once the storage element is charged, the circuit draws only 2.5 μA of current while it maintains the super capacitor or other storage element in its ready state. When the main supply is removed, the integrated reverse blocking switch will block current flow from system rail to input. The linear charger will be turned on to provide power to system rail with low resistance path with up to 2 A current. Integrated cell balancing circuit will keep monitoring the cell voltage when charging and keep the two cells voltage at same level. The LS0502SCD33 is externally programmable for input current limit, input overvoltage, charge current limit, and charge voltage limit. It provides a flag signal when input supply is unplugged so that main system can taking action. LS0502SCD33 is available in DFN3X3-10 package.
