Note 1: Can support 1, 2 or 3 cells by shorting each cell. However, be sure to connect a battery for V3 cell.
Note 2: When connecting batteries, be sure to connect in the following order: GND
Note 3: Output may go ON momentarily when starting up power supply. If this error output during startup
Note 4: Please confirm operation when making connections other than the above.
Note 5: The input resistance for each cell should be 1kΩ or lower. Also, please select the appropriate value
Note: Output goes high simultaneously with overcharge detection at Ct pin short and open.
