Resistor connection pin for setting non-reversed input potential of comparator 1
Reversed input of comparator 1 (for charge current detection)
Non-reversed input of comparator 1 (for charge current detection)
Microcontroller signal input pin
Resistor connection pin for setting non-reversed input potential of comparator 2
Reversed input of comparator 2 (for countercurrent detection when 2 batteries are used)
Non-reversed input of comparator 2 (for countercurrent detection when 2 batteries are used)
No connection
No connection
Substrate of this IC (Lowest potential)
Charging signal input pin, charge with low
Charge prohibition signal input pin, charge prohibition with low (becomes low during discharge mode
for lithium-ion battery that set operates on)
On/off control pin of this IC, except Gate block (becomes "Open" during discharge mode for
lithium-ion battery that set operates on)
Power supply input
Gate connection pin of external power MOSFETs
Lithium-ion battery + side input pin
Note: * If negative voltage is applied due to countercurrent, etc., up to 1.5 mA can be allowed.
