: OFF, SW1=GND : ON
Goes OFF when open as it is pulled up to V
CC
.
Low voltage detection circuit ON/OFF control input pin.
SW2=V
CC
: OFF, SW2=GND : ON
Goes OFF when open as it is pulled up to V
CC
.
Low voltage detection circuit output pin.
NPN-Tr open collector output; goes ON (low level) for low voltage.
Ground pin.
Current detection pin. Detects current when external resistor voltage drops and
controls current. Reference voltage 0.1V=external resistance current value
Battery voltage input pin
*
Six types depending on rank : 4.1V, 8.2V, 12.3V, 4.2V, 8.4V, 12.6V, (TYP.)
Constant voltage circuit output pin. Controls external P-MOS FET gate and
charges constant voltage.
Power supply input pin.
*
G : Constant voltage circuit input pin
External resistance ratio (R1 : R2) enables setting constant voltage circuit output voltage.
Low voltage detection voltage is set for one cell (4.1V or 4.2V).
