The S-8264A/B/C Series is used for secondary protection of lithium-ion rechargeable batteries, and incorporates a high-accuracy voltage detection circuit and a delay circuit. Short-circuits between cells accommodate series connection of two to four cells.
Features
High-accuracy voltage detection circuit for each cell
Overcharge detection voltage n (n = 1 to 4) 4.20 V to 4.80 V (in 50 mV steps) Accuracy ±25 mV (+25°C), Accuracy ±30 mV (-5°C to +55°C)
Overcharge hysteresis voltage n (n = 1 to 4) -0.52 ±0.21 V, -0.39 ±0.16 V, -0.26 ±0.11 V, -0.13 ±0.06 V, None
Delay times for overcharge detection can be set by an internal circuit only (external capacitors are unnecessary)
