Description

General part information

LTC4000 Series

The LTC4000 is a high voltage, high performance controller that converts many externally compensated DC/DC power supplies into full-featured battery chargers.Features of the LTC4000’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 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.The LTC4000 is available in a low profile 28-lead 4mm × 5mm QFN and SSOP packages.LTC4000LTC4000-1Input Voltage Regulation MPPCNoYesInput Current MonitoringYesYesInput Current RegulationYesNoApplicationsHigh Power Battery Charger SystemsHigh Performance Portable InstrumentsIndustrial Battery Equipped DevicesNotebook/Subnotebook Computers
