Product Overview

The LTC4000EUFD-1#PBF is a high-performance High-voltage Controller for battery charging. It converts many externally compensated DC/DC power supplies into full-featured battery chargers with maximum power point control. The LTC4000-1 has an input voltage regulation loop instead of the input current regulation loop. The battery charger features 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 protection. Another external PFET provides low loss charging or discharging of the battery.
  • Solar panel input compatible
  • Complete high performance battery charger when paired with a DC/DC converter
  • Input ideal diode for low loss reverse blocking and load sharing
  • Output ideal diode for low loss PowerPath™ and load sharing with the battery
  • ±1% Accurate programmable charge current accuracy
  • ±0.25% Accurate programmable float voltage
  • Programmable C/X or timer based charge termination
  • NTC input for temperature qualified charging
