Learn MoreMost super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.
Eventually, the super capacitor voltage, and therefore the charging circuit's operating efficiency, increases so the capacitor charges at the desired constant (fast or max) charge current, ICHG, until it reaches and remains at constant voltage (CV) regulation voltage, VREG.
The converter operates in CV mode indefinitely to keep the supercap charged to 5 V. Due to large selection of Li-ion chargers on the market, it seems reasonable to use a Li-ion charger to charge a supercapacitor. A Li-ion charge profile is show in Figure 2-6. Figure 2-6. Li-ion Charge Profile
All trademarks are the property of their respective owners. Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current.
A complete charge cycle using the BQ24640 to charge a 10 F supercapacitor to 5 V with ICHG=4A and V (adapter) = 24 V is shown in Figure 2-5. Figure 2-5. BQ24640 Charge Cycle of a 10 F Supercap with ICHG = 4 A Note that to protect the power FETs, while the supercap voltage is less than 2.1 V, the ISET pin is clamped to 600 mV.
Supercap Charging Profile With a fully discharged supercap, the charging circuit initially sends current directly to ground. The charging circuit operates at a much-reduced, slowly increasing current due to the converter die temperature reaching thermal regulation.
