Battery Full Signal, referenced to GND-AUX(Pin 9 & 10).
Charger OK Signal, referenced to GND-AUX(Pin 9 & 10).
The Signal is a TTL level signal. The maximum sourcing current is 10mA and only for output.(Note.2)
The Signal is a TTL level signal. The maximum sourcing current is 10mA and only for output.(Note.2)
Low (-0.5 ~ 0.5V) : When the battery is charging.
Low (-0.5 ~ 0.5V) : When the charger fails or the protect function is activating.
High (4.5 ~ 5.5V) : When the battery is full.
It is controlled by the Remote ON-OFF control.
High (4.5 ~ 5.5V) : When the charger is working properly.
The signal return is isolated from the output terminal. (+V & -V)
