S-8253BAA-T8T1GZ

S-8253BAA-T8T1GZ - BATTERY PROTECTION IC FOR 2-SERIAL OR 3-SERIAL-CELL PACK

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 

(1) High-accuracy voltage detection for each cell 

• Overcharge detection voltage n (n = 1 to 3) 3.9 V to 4.4 V (50 mV steps) Accuracy ±25 mV 

• Overcharge release voltage n (n = 1 to 3) 3.8 V to 4.4 V *1 Accuracy ±50 mV 

• 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) 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 to 24 V 

(8) Wide operating temperature range −40 to +85 °C 

(9) Low current consumption 

• Operation mode 28 µA max. (+25 °C) 

• Power-down mode 0.1 µA max. (+25 °C) 

(10) Lead-free products 

*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 to 0.4 V in 

50 mV steps.) 

*2. Overdischarge release voltage = Overdischarge detection 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 to 0.7 V in 

100 mV steps.)
