„ DESCRIPTION
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.
„ FEATURES
* Programmable Charge Current Up to 500mA.
* No External MOSFET, Sense Resistor or Blocking Diode Required.
* Complete linear charger in ThinSOT Package for Single Cell / Coin
Cell Lithium-lon Batteries.
* Constant Current / Constant Voltage Operation with Thermal
Regulation to Maximize Charge Rate Without Risk of Overheating.
* Charges Single Cell Li-lon Batteries Directly form USB Port.
* Preset 4.2V Charge Voltage with High Accuracy about ±1.2%.
* Automatic Recharge.
* 2.9V Trickle Charge Threshold.
* 20µA Supply Current in Shutdown Mode.
* Charge Status Output Pin.

DESCRIPTION
Open-Drain Charge Status Output. When the battery is charging, the CHRG pin is pulled
low by an internal N-channel MOSFET. When the charge cycle is completed, a weak
pull-down of approximately 20uA is connected to the CHRG pin, indicating an “AC
present” condition.
Ground.
Charge Current Output. Provides charge current to the battery and regulates the final
float voltage to 4.2V.
Positive Input Supply Voltage. Provides power to the charger. VCC can range from 4.5V
to 6.0V and should be bypassed with at least a 1μF capacitor.
Open-Drain Charge Termination Status Output. When the battery is charging, the
CHRGT pin is pulled high by an external component such as an LED. After the charging
is completed, this pin is pulled low by internal N-channel MOSFET and it can be used as
a charging termination indicator.
Charge Current Program, Charge Current Monitor and Shutdown Pin.
