Overview
The CN3125 is a complete constant-current /constant voltage linear charger IC to charge single cell or 2-cell superCapacitors from a power supply of 2.7V to 6V. The device contains an on-chip power MOSFET and eliminates the need for the external sense resistor and blocking diode. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The regulation voltage is externally set by a resistor divider. The charge current can be set externally with a single resistor. An internal active balancing circuit maintains equal voltages across each supercapacitor. When the input supply is removed, the CN3125 automatically enters a low power sleep mode, dropping the supercapacitor current to less than 3uA. Other features include chip enable, undervoltage lockout and supercapacitor power good indicator. The CN3125 is available in a thermally enhanced 8-pin SOP package.
