The adapter mode (Adapter standby mode) goes into effect when both the battery and the adapter

are not connected. The fixed voltage mode (7.2V) is set.

(2) Detection of Adapter

Adpt SW is used for detection of Adapter. When this terminal goes "H", Adapter is judged to be

present. If Adapter is connected during charging, charging is discontinued and the Adapter Mode goes

into effect. (The Adapter Mode has priority.)

(3) Setting Up the Output Voltage

The output voltage at the time of the Adapter Mode is set the internally set 7.2V.

(4) Protection Function

The over-current protection function is the only one protective function active during the Adapter Mode.

The current value is set by the voltage at the OCSET terminal. When the over-current is detected, the

output is controlled as shown in the following flow chart, The RESET will take place when Adpt SW

terminal goes "L".
