LTC4000-1 High Voltage High Current Controller for Battery Charging with Maximum Power Point Control DescripTion
The LTC®4000-1 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 LTC4000, the LTC4000-1 has an input voltage regulation loop instead of the input current regulation loop. Features of the LTC4000-1'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. The LTC4000-1 supports intelligent PowerPath control. An external PFET provides low loss reverse current protect
