7.6 Recommended Cell Balancing Configurations
Typical values stated where TA = 25°C and (VC2–VC1), (VC1–GND) = 3.8 V. Minimum and maximum values stated where
TA = –40°C to 110°C, VDD = 4 V to 10 V, and (VC2–VC1), (VC1–GND) = 3 V to 4.2 V. All values assume recommended
supply voltage filter resistance RVD of 100 Ω and 5% accurate or better cell balance resistor RCB.
