

Operation

Remark Refer to " Battery Protection IC Connection Examples".

1. Normal status

If the voltage of each of the batteries is lower than "the overcharge detection voltage n (VCUn)

+ the overcharge

hysteresis voltage n (VHCn)", the CO pin output changes to "L" (Active "H") or "H" (Active L"). This is called normal

status.

2. Overcharge status

When the voltage of one of the batteries exceeds VCUn during charging under normal conditions and the status is

retained for the overcharge detection delay time (tCU) or longer, the CO pin output changes. This is called overcharge

status. Connecting FET to the CO pin provides charge control and a second protection.

If the voltage of each of the batteries is lower than VCUn

+ VHCn and the status is retained for 2.0 ms typ. or longer, the

S-8215A Series changes to normal status.

3. Overcharge timer reset

When an overcharge release noise that forces the voltage of one of the batteries temporarily below VCUn is input during

tCU from when VCUn is exceeded to when charging is stopped, tCU is continuously counted if the time the overcharge

release noise persists is shorter than the overcharge timer reset delay time (tTR). Under the same conditions, if the time

the overcharge release noise persists is tTR or longer, counting of tCU is reset once. After that, when VCUn has been

exceeded, counting tCU resumes.
