description The LTC4000 is a high voltage, high performance controller that converts many externally compensated DC/DC power supplies into a full-featured battery charger. The LTC4000's battery charger features include: accurate (±0.25%) programmable floating voltage, optional timer or current charge termination, NTC thermistor for proper temperature charging, automatic recharge, for deep discharge C/10 trickle charge, dead battery detection, and status indicator output for the battery. In addition, the battery charger has precise current sensing capability to provide a low detection voltage for high current applications. The LTC4000 supports intelligent PowerPath control. An external PFET is used to provide low loss reverse current protection. Another external PFET is responsible for providing low-loss charging or discharging of the battery. This second PFET also facilitates an “on-the-fly†feature that provides immediate downstream system power even when connected to a battery that is severely discharged or short-circuited. The LTC4000 is available in a low profile 28-pin 4mm x 5mm QFN package and SSOP package.
