Product Overview

The UC3906N is a Battery Charger Controller IC contains all of the necessary circuitry to optimally control the charge and hold cycle for sealed lead-acid batteries. This integrated circuit monitor and control both the output voltage and current of the charger through three separate charge states, a high current bulk-charge state, a controlled over-charge and a precision float-charge or standby, state. Optimum charging conditions are maintained over an extended temperature range with an internal reference that tracks the nominal temperature characteristics of the lead-acid cell. A typical standby supply current requirement of only 1.6mA allows this IC to predictably monitor ambient temperatures. Separate voltage loop and current limit amplifiers regulate the output voltage and current levels in the charger by controlling the onboard driver.
  • Optimum control for maximum battery capacity and life
  • Internal state logic provides three charge states
  • Precision reference tracks battery requirements over-temperature
  • System interface functions
  • 1.6mA Typical standby supply current
