BATTERY PROTECTION IC
FOR 2-SERIAL OR 3-SERIAL-CELL PACK
S-8253A/B Series
The S-8253A/B Series are protection ICs for 2-serial or 3-serial cell
lithium-ion rechargeable batteries and include high-accuracy
voltage detectors and delay circuits.
These ICs are suitable for protecting lithium-ion battery packs from
overcharge, overdischarge and overcurrent.
Features
www.DataSheet4U.com
(1) High-accuracy voltage detection for each cell
Overcharge detection voltage n (n = 1 to 3)
Overcharge release voltage n (n = 1 to 3)
3.9 V to 4.4 V (50 mV steps) Accuracy ±25 mV
3.8 V to 4.4 V*1
Accuracy ±50 mV
*1. Overcharge release voltage = Overcharge detection voltage Overcharge hysteresis voltage
(Overcharge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.1 V to
0.4 V in 50 mV steps.)
Overdischarge detection voltage n (n = 1 to 3) 2.0 V to 3.0 V (100 mV steps) Accuracy ±80 mV
Overdischarge release voltage n (n = 1 to 3) 2.0 V to 3.4 V*2
Accuracy ±100 mV
*2. Overdischarge release voltage = Overdischarge release voltage Overdischarge hysteresis
voltage
(Overdischarge hysteresis voltage n (n = 1 to 3) can be selected as 0 V or from a range of 0.2 V to
0.7 V in 100 mV steps.)
(2) Three-level overcurrent detection (including load short circuiting detection)
Overcurrent detection voltage 1
0.05 V to 0.30 V (50 mV steps) Accuracy ±25 mV
Overcurrent detection voltage 2
0.5 V (fixed)
Overcurrent detection voltage 3
1.2 V (fixed)
(3) Delay times (overcharge, overdischarge, overcurrent) are generated by an internal circuit (external
capacitors are unnecessary).
(4) Charge/discharge operation can be inhibited via the control pin.
(5) 0 V battery charge function available/unavailable are selectable.
(6) High-voltage withstand devices
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
Operation mode
28 µA max. (+25°C)
Power-down mode
0.1 µA max. (+25°C)
Applications
Lithium-ion rechargeable battery packs
Lithium polymer rechargeable battery packs
Package
8-Pin TSSOP (Package drawing code: FT008-D)
