应用须知
- U-104 Improved Charging Methods for Lead-Acid Batteries Using the UC3906PDF, 331 Kb, 档案已发布: 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 ChargerPDF, 206 Kb, 档案已发布: 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
