S-8215A

S-8215A Series www.ablicinc.com © ABLIC Inc., 2010-2017 BATTERY PROTECTION IC FOR 3-SERIAL TO 5-SERIAL CELL PACK (SECONDARY PROTECTION) Rev.2.5_01 The S-8215A Series is used for secondary protection of lithium-ion rechargeable batteries, and incorporates high-accuracy voltage detection circuits and delay circuits. Short-circuiting between cells makes it possible for serial connection of three cells to five cells.  Features  High-accuracy voltage detection circuit for each cell Overcharge detection voltage n (n = 1 to 5) 3.600 V to 4.700 V (50 mV step) Accuracy 25 mV (Ta = 25C) Accuracy 30 mV (Ta = 5C to 55C) Overcharge hysteresis voltage n (n = 1 to 5) 0.0 mV to 550 mV (50 mV step) 300 mV to 550 mV Accuracy 20% 100 mV to 250 mV Accuracy 50 mV 0.0 mV to 50 mV Accuracy 25 mV  Delay times for overcharge detection can be set by an internal circuit only (External capacitors are unnecessary).  Output form is s...
