BATTERY PROTECTION IC
FOR 2-SERIES OR 3-SERIES-CELL PACK
Rev.2.5_00
The S-8253C/D Series is a protection ICs for 2-series or 3-series cell lithium-ion rechargeable battery and includes high-
accuracy voltage detector and delay circuit.
This IC is suitable for protecting lithium-ion battery packs from overcharge, overdischarge and overcurrent.
Features
(1) High-accuracy voltage detection for each cell
Overcharge detection voltage n (n = 1 to 3)
Overcharge release voltage n (n = 1 to 3)
3.900 V to 4.400 V (50 mV step) Accuracy ±25 mV
3.800 V to 4.400 V *1
Accuracy ±50 mV
Overdischarge detection voltage n (n = 1 to 3)
Overdischarge release voltage n (n = 1 to 3)
2.000 V to 3.000 V (100 mV step) Accuracy ±80 mV
2.000 V to 3.400 V *2
Accuracy ±100 mV
(2) Three-level overcurrent detection (Including load short circuiting detection)
Overcurrent detection voltage 1 0.050 V to 0.300 V (50 mV step)
Accuracy ±25 mV
Overcurrent detection voltage 2 0.500 V (Fixed)
Overcurrent detection voltage 3 1.200 V (Fixed)
(3) Delay time (Overcharge, overdischarge, overcurrent) is available by only using an internal circuit. (External
capacitors are unnecessary).
(4) Charge / discharge operation can be inhibited by the control pin.
(5) 0 V battery charge function available / unavailable is selectable.
(6) High-withstand voltage
Absolute maximum rating 26 V
(7) Wide range of operating voltage
2 V to 24 V
(8) Wide range of operating temperature 40°C to +85°C
(9) Low current consumption
During operation
28 μA max. (+25°C)
During power-down 0.1 μA max. (+25°C)
(10) Lead-free, Sn100%, halogen-free*3
*1. Overcharge release voltage = Overcharge detection voltage Overcharge hysteresis voltage
(Overcharge hysteresis voltage n (n = 1 to 3) can be selected in 0 V, or in 0.1 V to 0.4 V in 50 mV step.)
*2. Overdischarge release voltage = Overdischarge detection voltage + Overdischarge hysteresis voltage
(Overdischarge hysteresis voltage n (n = 1 to 3) can be selected in 0 V, or in 0.2 V to 0.7 V in 100 mV step.)
*3. Refer to “Product Name Structure” for details.
Applications
Lithium-ion rechargeable battery packs
Lithium polymer rechargeable battery packs
Package
8-Pin TSSOP
