Pin Name
Function
LED drive (Open collector outputs)
Setting the oscillating frequency of the internal clocks.
The SW drive terminal used for charging battery. (Open collector outputs)
Ground
Checking whether a battery is mounted or not. (It has a pull-up resistor)
Detecting VTR connection. (It has a pull-up resistor)
Test mode set-up. (It has a pull-up resistor)
This is connected to the + terminal of the battery.
This is connected to the – terminal of the battery.
This is connected to the temperature detecting terminal of the battery.
The voltage reference terminal for temperature detection.
This is connected to the photo-coupler used for feedback.
(It has a pull-up resistor)
Monitoring the output voltage.
Detecting the charging current or output current.
Setting the over-current detection value in the adapter mode.
These are used to the charging current.
(I
SET1
is for quick charge and I
SET2
is for trickle charge)
Setting the standard voltage for over-current set-up value and the charge
current set-up.
Power supply.
