LS0502SCD33S

Single Cell Super Capacitor Protection IC for Backup Power Applications

RoHS Pb

Description

The LS0502SCD33S is a complete solution for system with

backup storage capacitor or capacitor bank. It integrates input

overvoltage, overcurrent protection circuit, a reverse blocking

switch and super capacitor charging control circuit.

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.

The LS0502SCD33S 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. LS0502SCD33S is available in

DFN3X3-10 package.
