BATTERY PROTECTION IC FOR 1-CELL PACK
S-82A1A Series
8. Delay circuit
The detection delay times are determined by dividing a clock of approximately 4 kHz by the counter.
Remark
t_DIOV1, t_DIOV2 and t_SHORT start when V_DIOV1 is detected. When V_DIOV2 or V_SHORT is detected over t_DIOV2 or t_SHORT
after the detection of V_DIOV1, the S-82A1A Series turns the discharge control FET off within t_DIOV2 or t_SHORT of
each detection.
