2. Adapter Mode Operation

(1) Adapter mode

The adapter mode (adapter standby mode) goes into effect when both the battery and the adapter are not connected.

The fixed voltage mode (7.2 V) 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 7.2 V.

(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".
