(When CT is shorted)

(When CT is open)

Note : When pin Ct is shorted or left open, the output goes low when overcharging is detected.

Application Circuits

Note : By shorting each cell, two-, three- and four-cell series can be accommodated. A V4 cell should always

be connected. If the V4 cell is shorted, the chip may not function correctly.
