Supercapacitor Chargers

Supercapacitors, capacitors with up to 100F of charge storage, are emerging as an alternative to batteries in applications where the importance of power delivery trumps that of total energy storage. Supercapacitors have a number of advantages over batteries that make them a superior solution when short term, high power is needed, such as in power ride-through applications. These advantages include lower effective series resistance (ESR) and enhanced durability in the face of repeated charging.

Linear Technology offers a portfolio of linear, switching and switched capacitor ICs designed to charge supercapacitors (also known as ultracapacitors).  These parts offer input or output current limiting, automatic cell balancing and a range of protection features that make them uniquely suited to super cap charging.
