Set the cell balancing current value so that R CB does not exceed the power dissipation.
Cautions 1. The above constants may be changed without notice.

 Operation
Remark
Refer to " Standard Circuit ".
1. Normal status
In the S-19190 Series, if the voltage between the VDD pin and the VSS pin (V DS ) has not reached the cell
balancing detection voltage (V BU ), the CB pin output is in the high-impedance status. The CO pin output status
varies according to the output form and output logic selected, as shown in Table 11. This is the normal status.

2. Cell balancing status
In the S-19190 Series, if V DS is V BU or higher and this status continues for the cell balancing detection delay time
(t BU ) or longer, the CB pin output becomes "L". This is the cell balancing status.
The cell balancing status is released when V DS drops to the cell balancing release voltage (V BL ) or lower and this
status continues for the cell balancing release delay time (tBL ) or longer.
The S-19190 Series includes an Nch transistor with ON resistance of 5 Ω typ. (R CBON ) between the CB pin and the
VSS pin, thus causing the cell balancing current (I CB ) to flow in cell balancing status, and the cell balancing
operation to start.
By connecting a resistor (R CB ) to the CB pin, I CB in cell balancing status can be calculated by using the following
equation.
I CB = V BU / (R CBON + R CB )

In the S-19190 Series, if VDS is the overcharge detection voltage (V CU ) or higher and this status continues for
the overcharge detection delay time (t CU ) or longer, the CO pin output is inverted. The CO pin output status
varies according to the output form and output logic selected, as shown in Table 12. This is the overcharge
status. In the overcharge status, the CB pin output becomes "L".

The overcharge status is released when VDS drops to the overcharge release voltage (V CL ) or lower and this
status continues for the overcharge release delay time (t CL ) or longer.

4. CE pin
_____
The S-19190 Series has the CE pin (Power-saving mode switching
pin). The S-19190 Series is set to
_____
power-saving mode by inputting a voltage of V C E H or higher to the CE pin.

_____
_____
_____
_____
In power-saving mode, the current consumption is decreased to current consumption during power-saving (I PSV ).
The CB pin or the CO pin output in power-saving mode is the same as that in the normal status.
_____
The_____
CE pin is pulled down to V SS by the internal resistor. When in a mode other than power-saving mode, leave
the CE pin open or short it with V SS .

5. DP pin
The S-19190 Series has the DP pin (Test mode switching pin). The S-19190 Series is set to test mode (used to
shorten the delay time) by inputting a voltage of V DPH or higher to the DP pin.

Test mode
Normal operation mode
In test mode, the cell balancing detection delay time (t BU ) and overcharge detection delay time (t CU ) are
shortened to 1/64 of the delay time in the normal operation mode.
The DP pin is pulled down to VSS by the internal resistor. When in a mode other than test mode, leave the DP
pin open or short it with V SS .
