Product Description

The UC3906N is a Linear Lead-Acid Battery Charger features precision reference tracks battery requirements over-temperature. The UC2906 series of battery charger controller 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 these ICs 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
Controls both voltage and current at charger output
