The LTC3225EDDB-1#PBF from LT is a programmable supercapacitor charger designed to efficiently charge two supercapacitors connected in series. It operates from input supply voltages ranging from 2.8V to 5.5V and provides selectable output voltages suitable for supercapacitor charging.
A key feature of this device is its automatic cell balancing capability, which prevents overvoltage damage to individual supercapacitors without the need for external balancing resistors. The charger operates with low noise and a constant frequency, ensuring stable charging performance.
This supercapacitor charger supports a programmable charge current of up to 150mA. It also features selectable regulation voltages per cell, with options for 2.4V or 2.65V for the LTC3225 variant and 2V or 2.25V for the LTC3225-1 variant. The device consumes very low current in standby mode (20µA) and shutdown mode (0.1µA).
The LTC3225EDDB-1#PBF is housed in a compact 3x2mm DFN-10 package, making it suitable for space-constrained applications. Its operating temperature range is from 0°C to 85°C.
