Battery Management
New high-frequency switch-mode Li-Ion battery charger simplifies constant current control in quick-charge portables. The ADP3806 is a stand-alone Li-Ion battery-charging IC that combines high output voltage accuracy with precise current control to improve the performance and reduce the design complexity of Constant-Current, Constant-Voltage (CCCV) chargers. The industry’s highest end-of-voltage accuracy levels are achieved to within ±0.4% at 25ºC, ±0.6% at 5ºC to 55ºC and ±0.7% at 0ºC to 85ºC.
