DC1220B is a Low Profile Regulated Dual Cell SuperCAP Charger featuring the LTC3225. The LTC3225 is a constant-current SuperCAP charger designed to charge two SuperCAPs in series to a fixed output voltage of 4.8V/5.3V from a 2.9V to 5.5V input supply. Automatic cell balancing is achieved during the charging phase.
Low input noise, low quiescent current and low external parts count make the LTC3225 ideally suited for small, battery-powered applications. Charging current level is programmed through an external resistor. Internal current limit and thermal shutdown circuitry allows the part to survive a continuous short-circuit from PROG to GND.
When the input supply is removed, the LTC3225 automatically enters a low current state, drawing less than 1µA from the SuperCAPs.
