Product Overview

The LTC4089EDJC#PBF is an USB Power Manager with high voltage switching charger. This device controls the total current used by the USB peripheral for operation and battery charging. Battery charge current is automatically reduced such that the sum of the load current and the charge current does not exceed the programmed input current limit. The LTC4089 also accommodate high voltage power supplies, such as 12V AC-DC wall adapters, FireWire or automotive power. The LTC4089 provides an adaptive output that tracks the battery voltage for high efficiency charging from the high voltage input. The charge current is programmable and an end-of-charge status output (CHRG) indicates full charge. Also featured is programmable total charge time, an NTC thermistor input used to monitor battery temperature while charging and automatic recharging of the battery.
  • Seamless transition between input power sources (Li-ion battery, USB and 6 to 36V external supply)
  • High efficiency 1.2A charger from 6 to 36V input with adaptive output control
  • Load dependent charging guarantees accurate USB input current compliance
  • Constant-current/constant-voltage operation with thermal feedback
  • Maximize charging rate without risk of overheating
  • Selectable 100 or 20% input current limit (e.g. 500/100mA) from USB input
  • Preset 4.2V charge voltage with 0.8% accuracy
  • C/10 charge current detection output
  • NTC thermistor input for temperature qualified charging
