LTC4000IGN-1#PBF

LTC4000-1 is a high voltage, high performance controller that converts many externally compensated DC/DC power supplies into full-featured battery chargers with maximum power point control. In contrast to the device has an input voltage regulation loop instead of the input current regulation loop. Features of the device’s battery charger include accurate (±0.25%) programmable float voltage, selectable timer or current termination, temperature qualified charging using an NTC thermistor, automatic recharge, C/10 trickle charge for deeply discharged cells, bad battery detection and status indicator outputs. The battery charger also includes precision current sensing that allows lower sense voltages for high current applications. It is widely used in applications such as solar powered battery charger systems, battery charger with high impedance input source, e.g., fuel cell or wind turbine, battery equipped industrial or portable military equipment's.
