1

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)

• Overcharge detection voltage n (n = 1 to 3)

3.900 V to 4.400 V (50 mV step)

Accuracy

±25 mV

• Overcharge release voltage n (n = 1 to 3)

3.800 V to 4.400 V

*1

Accuracy

±50 mV

• Overdischarge detection voltage n (n = 1 to 3)

2.000 V to 3.000 V (100 mV step) Accuracy

±80 mV

• Overdischarge release voltage n (n = 1 to 3)

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

• During power-down

0.1

(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.
