Q1-5
*1. If R1-5 connects with an over-spec resistor, battery accuracy may be influenced due to R1-5 voltage
drop that caused by current consumption. When a charger is connected in reversed, the current flows
from the charger to the IC. At this time, if R1-5 is too high, the voltage between VDD pin and VSS pin may
exceed the absolute maximum rating.
*2. If RB1-5 connects with an under-spec resistor, the charge current will become large all of a sudden
when battery voltage exceeded overcharge detection voltage (VCU), which may lead to charge
over-current and the circuit will be protected and could not be charged.
*3. C1-5 can stabilize the supply voltage of VDD, the value of C1-5 should larger than 0.01μF.
*4. Select N-MOSFET or P-MOSFET according to different model no.
Caution：
