资 源 简 介

The LTC4425 is a constant-current/constant-voltage linearcharger designed to charge a 2-cell supercap stack fromeither a Li-Ion/Polymer battery, a USB port, or a 2.7V to5.5V current-limited supply. The part operates as an idealdiode with an extremely low 50mΩ on-resistance making itsuitable for high peak-power/low average power applicaTIons.The LTC4425 charges the output capacitors to an externallyprogrammed output voltage in LDO mode at a constantcharge current, or to VIN in normal mode with a smart chargecurrent profi le to limit the inrush current unTIl the VIN to VOUTdifferenTIal is less than 250mV. In addiTIon the LTC4425 canbe set to clamp the output voltage to 4.9V or 5.4V.
