AAT3680

Lithium-Ion Linear Battery Charge Controller

Constant Voltage Charging

Charge Cycle Termination, Recharge

Sequence

When the battery's voltage reaches V_CHduring

constant-current mode, the AAT3680 transitions to

constant-voltage mode. The regulation voltage is

factory programmed: 4.1V and 4.2V (or 8.2V and

8.4V for two-cell applications) are available to sup-

port different anode materials in Lithium Ion cells.

In constant-voltage operation, the AAT3680 moni-

tors the cell voltage and terminates the charging

cycle when the voltage across R_SENSEdecreases to

approximately 10mV.

After the charge cycle is complete, the AAT3680

latches off the pass device and automatically enters

power-saving sleep mode. Either of two possible

conditions will bring the IC out of sleep mode: the

battery voltage at the BAT pin drops below V_RCH

(recharge threshold voltage) or the AAT3680 is reset

by cycling the input supply through the power-on

sequence. Falling below V_RCHsignals the IC that it

is time to initiate a new charge cycle.
