Functions of Terminal Explained
These terminals are used to set the oscillating frequency of the internal
clocks.
This is an input terminal used to detect the current which is used for the
discharge current feedback.
This is the drive terminal for the transistor mounted externally for discharge
purposes.
This is the SW drive terminal used for charging battery.
These are grounding terminals. (GND1 is for logic and GND2 is for analog.)
This is used to detect mounting of battery.(It is pulled up internally)
This is used to detect the discharge SW.(It is pulled up internally)
This is used to detect adapter SW.(It is pulled up internally)
These are Test Mode set-up terminal.(It is pulled up internally)
This terminal is connected to the + terminal of the battery.
This terminal is connected to the - terminal of the battery.
This terminal is connected to the temperature detecting terminal of the
battery.
This is the voltage reference terminal for temperature detection.
This terminal is used to set the over-current detection value when the
adapter mode is used.
These are used to set the charging current.(Iset1 is for quick charge and
Iset2 is for the trickle charge.)
This terminal is sets the standard voltage for over-current set-up value
and the charge current set-up.
