BATTERY PROTECTION IC FOR 3-SERIAL- OR 4-SERIAL-CELL PACK
 
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) 3.9 V to 4.4 V (50 mV step) Accuracy ±25 mV
•  Overcharge release voltage n (n = 1 to 4) 3.8 V to 4.4 V
*1
 Accuracy ±50 mV
•  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
•  Overcurrent detection voltage 3 VVC1 − 1.2 V Accuracy ±300 mV
(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) High-withstand voltage device Absolute maximum rating : 26 V
(7) Wide operating voltage range 2 V to 24 V
(8) Wide operating temperature range  −40°C to + 85°C
(9) Low current consumption
•  During operation 30 μA max. (+25°C)
•  During power-down 0.1 μA max. (+25°C)
(10) Lead-free, Sn100%, halogen-free
 
Applications
•  Lithium-ion rechargeable battery packs
