Product Overview

The LTC3225EDDB#TRMPBF is a programmable Supercapacitor Charger designed to charge two supercapacitors in series to a selectable fixed output voltage (4.8V/5.3V for the LTC3225) from input supplies as low as 2.8 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 VIN and one programming resistor) make the LTC3225 ideally suited for small battery-powered applications. Charge current level is programmed with an external resistor. When the input supply is removed, the LTC3225 automatically enter a low current state, drawing less than 1µA from the super capacitors.
  • Low noise constant frequency charging of two series super capacitors
  • Automatic cell balancing prevents capacitor overvoltage during charging
  • Programmable charge current (up to 150mA)
  • Automatic recharge
  • No inductors
