Product Overview

The LTC4000IGN-1#PBF is a high voltage, high current Controller for battery charging. The high performance controller that converts many externally compensated DC/DC power supplies into full-featured battery chargers. It 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. This second PFET also facilitates an instant-on feature that provides immediate downstream system power even when connected to a heavily discharged or short faulted battery.
  • Input ideal diode for low loss reverse blocking and load sharing
  • Output ideal diode for low loss PowerPath™ and load sharing with battery
  • Instant-on operation with heavily discharged battery
  • ±1% Accuracy programmable input and charge current
  • ±0.25% Accurate programmable float voltage
  • Programmable C/X or timer based charge termination
  • NTC Input for temperature qualified charging
