Detailed description

S-8253AAA- BATTERY PROTECTION IC FOR 2-SERIAL OR 3-SERIAL-CELL PACK - Seiko Instruments Inc

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.)
