Product Summary

The UC2906DWG4 of battery charger controller contains all of the necessary circuitry to optimally control the charge and hold cycle for sealed lead-acid batteries. The UC2906DWG4 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 these ICs to predictably monitor ambient temperatures.
