BATTERY PROTECTION IC FOR 2-SERIAL TO 4-SERIAL-CELL PACK (SECONDARY PROTECTION)
Rev.4.7_00
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-circuiting between cells makes it possible for serial connection of two cells to four cells.
Features
(1) High-accuracy voltage detection circuit for each cell
• Overcharge detection voltage n (n = 1 to 4)
4.200 V to 4.800 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)
−0.520 ±0.210 V, −0.390 ±0.160 V, −0.260 ±0.110 V, −0.130 ±0.
