The LTC4041 is a complete supercapacitor backup system for 2.9V to 5.5V supply rails. It contains a high current step-down DC/DC converter to charge a single supercapacitor or two supercapacitors in series. When input power is unavailable, the step-down regulator operates in reverse as a step-up regulator to backup the systemoutput from the supercapacitor(s).
The LTC4041’s adjustable input current limit function reduces charge current to protect the input supply from overload while an external disconnect switch isolates theinput supply during backup. When the input supply drops below the adjustable PFI threshold, the 2.5A boost regulator delivers power from the supercapacitor to the systemoutput.
An optional input overvoltage protection (OVP) circuit protects the LTC4041 from high voltage damage at the VIN pin. An internal supercapacitor balancing circuit maintainsequal voltages across each supercapacitor and limits the maximum voltage of each supercapacitor to a pre-determined value. The LTC4041 is available in a low profile (0.75mm) 24-Lead 4mm × 5mm QFN package.
