5 Application Circuit Pack+ R1 330 VDD DS Oscillator Counter C1 VD1 Overcharge VD2 Overdischarge VD4 Charging Overcurrent VD3 Logic circuit Delay Logic circuit Level shift Charger Short C2 Discharging Overcurrent VSS DOUT COUT V R2 2.2k C3 Pack R1 and C1 stabilize a supply ripple. However, the detection rises by the current of penetration in IC of the detection when R1 is enlarged, and the value of R1 is adjusted to 1k or less. Moreover, adjust the value of C1 to 0.01µF or more to do the stability operation, please. R1 and R2 resistors are current limit resistance if a charger is connected reversibly or a high- charger that exceeds the absolute maximum rating is connected. R1 and R2 may cause a power consumption will be over rating of power dissipation, therefore the `R1+R2` should be more than 1k. Moreover, if R2 is too enlarged, the charger connection release cannot be occasionally done after the overdischarge is detected, so adjust the value of R2 to 10k or less, please. C2 and C3 capacitors have effect that the system stability about ripple or imported noise. After check characteristics, decide that these capacitors should be inserted or not, where should be inserted, and capacitance value, please.
