Product Overview

The LTC4006EGN-6#PBF is a high efficiency complete constant-current/constant-voltage Charger Controller for 2-, 3- or 4-cell lithium batteries in a small package using few external components. The PWM controller is a synchronous, quasi-constant frequency, constant off-time architecture that will not generate audible noise even when using ceramic capacitors. Charging current is programmable with a single sense resistor to ±4% typical accuracy. Charging current can be monitored as a representative voltage at the IMON pin. Charging terminates if the low-battery condition persists for more than 25% of the total charge time. It includes a thermistor sensor input that suspends charging if an unsafe temperature condition is detected and automatically resumes charging when the battery temperature returns to within safe limits. A timer, programmed by an external resistor, sets the total charge time or is reset to 25% of total charge time after C/10 charging current is reached.
  • Up to 96% high conversion efficiency
  • Built-in charge termination with automatic restart
  • AC adapter current limiting maximizes charge rate
  • Automatic conditioning of deeply discharged batteries
  • Thermistor input for temperature qualified charging
  • 98% Maximum duty cycle
  • Programmable charge current: ±4% accuracy
  • Charging current monitor output
