Description
Input Supply Voltage. Provides power to the charger. This pin should be bypassed with at least a 4.7 m F ceramic
capacitor to ground.
An open?drain output indicating fault status. This pin is pulled LOW under any fault conditions. A FAULT condition
resets the counter.
An open?drain output indicating charging or end?of?charge states. The CFLG pin is pulled LOW when the charger
is charging a battery. It is forced open when the charge current drops to I EOC . This high impedance mode will be
latched until a recharge cycle or a new charge cycle starts.
Connecting a timing capacitor, C TIME between this pin and ground to set end?of?charge timeout timer.
TIMEOUT = 14*C TIME /1.0 nF (minute). The total charge for CC and CV mode is limited to the length of TIMEOUT.
Trickle Charge has a time limit of 1/8 of the TIMEOUT period.
Ground pin of the IC. For thermal consideration, it is recommended to solder the exposed metal pad on the back-
side of the package to ground.
Enable logic input. Connect the EN pin to LOW to disable the charger or leave it floating to enable the charger.
2.8 V reference voltage output. This pin outputs a 2.8 V voltage source when an adapter is present. The maximum
loading for this pin is 2.0 mA.
The full charge current (I FCHG ) can be set by connecting a resistor, R ISEL , from the ISEL pin to ground.
For best accuracy, a resistor with 1% tolerance is recommended.
Battery voltage sense pin. Connect this as close as possible to the battery input connection.
Charge current output. A minimum 4.7 m F capacitor is needed for stability when the battery is not attached.
