Operation
In the S-8204B Series, both of COP and DOP pins get the V
range of overdischarge detection voltage (V
current, the VINI pin’s voltage is discharge overcurrent detection voltage (V
In addition, the charge/discharge FETs are on.
In the S-8204B Series, any voltage of the batteries increases to the level of V
impedance. This is the overcharge status. The COP pin is pulled down to EB− by an external resistor so that the
charge FET is turned off and it stops charging.
This overcharge status is released if either condition 1 or 2 is satisfied;
In the S-8204B Series, when any voltage of the batteries decreases to the level of V
gets the V
This overcharge status is released/maintained if either condition 1 to 3 is satisfied;
In the S-8204B Series, either the products with power-down function or those without power-down function can be
selected.

(1) To release; the VMP pin voltage is in the V
(2) To release; the VMP pin voltage is V
(3) The VMP pin voltage is V
When the S-8204B Series reaches the overdischarge status, the VMP pin is pulled down to the V
resistor between VMP and VSS pin (R
every circuit in the S-8204B Series stops working so that the current consumption decreases to the level of
current consumption at power down (I
The power-down status is released if the following condition is satisfied.
The VMP pin is not pulled down even when the S-8204B Series reaches the overdischarge status. The
overdischarge status is maintained even If the VMP pin voltage decreases to the level of V
current consumption decreases to the level of current consumption during overdischarge (I
