Supercapacitors may be used in short-term backup solutions where they act as a source of alternate power, as well as long-term backup solutions where they act as a source of primary power. There are several unique challenges when we attempt to use supercapacitors in a backup solution.
Supercapacitors can be charged quickly during normal operation and provide reliable backup power to retain the RTC data when primary power is lost. This document explores the use of supercapacitors as a backup power solution for the Abracon AB08X5 Real-Time clock family.
For optimal performance, a reliable, adaptable power management solution is vital. The LS0502SCD33 (dual channel solution) and the LS0502SCD33S (single channel solution) offer fully integrated power management solutions tailored for systems with supercapacitor backup power applications.
In backup operation mode, power is supplied from supercapacitor. Input Over Voltage/ Current Protection-HV Load Switch (M1) In any system the capacitor is initially discharged. When the supply voltage is applied, the supercapacitor looks like a low value resistor.
Traditionally, backup power for RTCs has been provided by small batteries or in some cases standard ceramic or polarized capacitors. However, supercapacitors (or ultracapacitors) are often considered an efective alternative due to their long cycle life, rapid charging, and ability to deliver sustained power over extended periods.
The duration of backup depends on the supercapacitor’s energy reserve and the system power draw. The features of the Maxim Integrated products allow for maximum backup power from a single 2.7-volt supercapacitor, while reducing the number of circuit components by eliminating the need for separate charger and boost devices, and diodes.
