ONE-CELL STANDALONE LINEAR LITHIUM BATTERY CHARGER
DESCRIPTION
UB2017 CMOS集成電路
單電池標準線性鋰電池充電器
描述
特徵
ONE-CELL STANDALONE LINEAR LITHIUM BATTERY CHARGER
DESCRIPTION
UTC UB2017 is a complete, constant current and constant voltage linear charger for single cell lithium-ion batteries. Its small size and ability to regulate low charge currents make UTC UB2017 especially well-suited for portable applications using low capacity rechargeable lithium-ion coin cells. Furthermore, UTC UB2017 is specifically designed to work within USB power specifications.
No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. UTC UB2017 automatically terminates a charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.

UB2017 CMOS集成電路
單電池標準線性鋰電池充電器
描述
UTC UB2017是用於單節鋰離子電池的完整，恆定電流和恆定電壓線性充電器。 UTC UB2017的體積小且能夠調節低充電電流，因此特別適合使用低容量可充電鋰離子鈕扣電池的便攜式應用。此外，UTC UB2017專為在USB電源規範內工作而設計。
由於採用了內部MOSFET架構，因此不需要外部檢測電阻，也不需要隔離二極管。充電電壓固定為4.2V，可通過單個電阻在外部對充電電流進行編程。當達到最終浮動電壓後，充電電流降至編程值的1/10時，UTC UB2017自動終止充電週期。
