... Overcharge Status When any one of the battery voltages becomes higher than V becomes high impedance. Because the COP pin is pulled up to the EB+ pin voltage by an external resistor, the charging FET is turned off to stop charging. This is called the overcharge status. The overcharge status is released when one of the following two conditions holds ...

... The S-8253A/B Series has a control pin for charge / discharge control and shortening the test time. The levels, “L”, “H”, and “M”, of the voltage input to the CTL pin determine the status of the S-8253A/B Series: normal operation, charge / discharge inhibition, or test time shortening. The CTL pin takes precedence over the battery protection circuit. During normal use, short the CTL pin and VSS pin ...
