    PDF, 331 Kb, File published: Sep 5, 1999
    This application note describes the operation and application of the UC3906 sealed lead-acid battery-charger IC. Several charging circuits using this IC are described, along with expected improvements in battery performance. This note also discusses uses for the many auxiliary functions of the part.
  • U-131 Simple Switchmode Lead-Acid Battery Charger
    PDF, 206 Kb, File published: Sep 5, 1999
    Lead-acid batteries are finding considerable use as bothprimary and backup power sources. For complete batteryutilization the charger circuit must charge the batteryto full capacity while minimizing over-charging forextended battery life. Since battery capacity varies withtemperature the charger must vary the amount of chargewith temperature to realize maximum capacity and life.Si
