Overview
UNISONIC TECHNOLOGIES CO.
, LTD UB6054A Preliminary CMOS IC ONE-CELL STANDALONE LINEAR LITHIUM BATTERY CHARGER „ DESCRIPTION 6 5 4 UTC UB6054A 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 UB6054A especially well-suited for portable applications using low capacity rechargeable lithium-ion coin cells.
Furthermore, UTC UB6054A 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 UB6054A automatically terminates a charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
1 2 3 SOT-26 „ FEATURES * Programmable Charge Current Up to 500mA.
* No External MOSFET, ...
