What is the selective range of the lithium-ion battery packs protection IC’s external resistor, R1?

It is advised to set R1 resistance between 100~470Ω. Due to current consumption, R1 should be as small as possible to avoid lowering the overcharge detection accuracy. When a charger is connected in reversed, the current flows from the charger to the IC. At this time, if R1 is connected to high resistance, the voltage between VDD pin and VSS pin may exceed the absolute maximum rating.
