The LS0502SCD33 from Littelfuse is an eFuse IC that has been designed as a complete solution for systems with a backup storage capacitor or capacitor bank. It requires an input voltage of 2.5 - 5.5 V. This eFuse IC features a programmable cap voltage range from 1.1 V to 5.3 V, a programmable supercapacitor charge current, and a programmable input over-current protection. It offers a built-in cell balance to monitor the cell voltage when charging and to keep the two cells voltage at the same level. This e-Fuse IC is programmable for input current limit, input overvoltage, charge current limit, and charge voltage limit. It offers an automatic main/backup switchover with a discharge current of up to 2 A. This eFuse IC is available in a surface-mount package that measures 3.10 x 3.10 x 0.80 mm and is ideal for handheld industrial equipment, dash cameras, smart meters, portable device with removable batteries and IoT applications.
