S-8254A Series www.ablic.com BATTERY PROTECTION IC FOR 3-SERIAL- OR 4-SERIAL-CELL PACK © ABLIC Inc., 2002-2019 Rev.5.3_00 The S-8254A Series is a protection IC for 3-serial- or 4-serial-cell lithium-ion / lithium polymer rechargeable batteries and includes a high-accuracy voltage detector and delay circuit. The S-8254A Series protects both 3-serial or 4-serial cells using the SEL pin for switching.  Features (1) High-accuracy voltage detection for each cell • Overcharge detection voltage n (n = 1 to 4) 3.90 V to 4.45 V (50 mV step) Accuracy ±25 mV Accuracy ±50 mV • Overcharge release voltage n (n = 1 to 4) 3.80 V to 4.45 V*1 • Overdischarge detection voltage n (n = 1 to 4) 2.0 V to 3.0 V (100 mV step) Accuracy ±80 mV • Overdischarge release voltage n (n = 1 to 4) 2.0 V to 3.4 V*2 Accuracy ±100 mV (2) Three-level overcurrent protection • Overcurrent detection voltage 1 0.05 V to 0.30 V (50 mV step) Accuracy ±25 mV • Overcurrent detection voltage 2 0.5 V Accuracy ±100 mV Accuracy ±300 mV • Overcurrent detection voltage 3 VVC1 − 1.2 V (3) Delay times for overcharge detection, overdischarge detection and overcurrent detection 1 can be set by external capacitors (delay times for overcurrent detection 2 and 3 are fixed internally). (4) Switchable between a 3-serial cell and 4-serial cell using the SEL pin (5) Charge/discharge operation can be controlled via the control pins. (6) 0 V battery charge Enabled, inhibited (7) Power-down function Available (8) High-withstand voltage Absolute maximum rating : 26 V (9) Wide operating voltage range 2 V to 24 V (10) Wide operating temperature range −40°C to + 85°C (11) Low current consumption • During operation 30 μA max. (+25°C) • During power-down 0.1 μA max. (+25°C) (12) Lead-free, Sn100%, halogen-free*3 *1. Overcharge hysteresis voltage n (n = 1 to 4) can be selected as 0 V or from a range of 0.1 V to 0.4 V in 50 mV steps. (Overcharge hysteresis voltage = Overcharge detection voltage − Overcharge release voltage) *2. Overdischarge hysteresis voltage n (n = 1 to 4) can be selected as 0 V or from a range of 0.2 V to 0.7 V in 100 mV steps. (Overdischarge hysteresis voltage = Overdischarge release voltage − Overdischarge detection voltage) *3. Refer to “ Product Name Structure” for details.  Applications • Lithium-ion rechargeable battery packs • Lithium polymer rechargeable battery packs  Package • 16-Pin TSSOP 1 PDF
