NJW4120  
Feature Description (Continued)  
Amp control and control of the SW transistor connected to the TX-SW pin are not the same in adapter output mode  
and charge control mode.  
1-1. Adapter output mode (ADP pin)  
In adapter output mode, each of the circuits in the control unit will be in the following state.  
ADP voltage control amp ON  
Charge voltage control amp OFF  
Charge current control amp OFF  
SW transistor OFF  
To set the adapter output voltage, use the ADP pin's external resistors RA1, and RA2 and the following formula.  
VADP  
=
RA1 + RA2 x VREF-ADP (1.24V)  
RA2  
In adapter output mode the SW transistor connected to the TX-SW pin will turn OFF, and charge to the battery will  
be cut off. For this reason, take adapter output voltage from a power supply line that comes before the SW transistor.  
1-2.Charge control mode  
In the case of pre-charge and quick charge each of the circuits in the control unit will be in the following state.  
ADP voltage control amp OFF  
Charge voltage control amp ON  
Charge current control amp ON  
SW transistor ON  
However, when there is 2mA of charge, the system will operate in adapter output mode (SW transistor OFF).  
The SW transistor turns ON, and battery charging will be performed.  
Charge voltage and charge current operations are described in "2. Voltage Detection Block", and "3. Current  
Detection Block".
