DESCRIPTION
The LTC
®
3225/LTC3225-1 are programmable supercapaci-
tor chargers designed to charge two supercapacitors in
series to a selectable fixed output voltage (4.8V/5.3V for
the LTC3225 and 4V/4.5V for the LTC3225-1) from input
supplies as low as 2.8V to 5.5V. Automatic cell balancing
prevents overvoltage damage to either supercapacitor. No
balancing resistors are required.
Low input noise, low quiescent current and low external
parts count (one flying capacitor, one bypass capacitor at
V
IN
and one programming resistor) make the LTC3225/
LTC3225-1 ideally suited for small battery-powered
applications.
Charge current level is programmed with an external
resistor. When the input supply is removed, the LTC3225/
LTC3225-1 automatically enter a low current state, drawing
less than 1μA from the supercapacitors.
The LTC3225/LTC3225-1 are available in a 10-lead 2mm
×
3mm DFN package.
