S-8225A Series

BATTERY MONITORING IC

FOR 3-SERIAL TO 5-SERIAL CELL PACK

www.sii-ic.com

Rev.1.7_02

The S-8225A Series includes high-accuracy voltage detection circuits and delay circuits, and can monitor the status of

3-serial to 5-serial cell lithium-ion rechargeable battery in single use. By switching the voltage level which is applied to the

SEL1 pin and SEL2 pin, users are able to use the S-8225A Series for 3-serial to 5-serial cell pack.

By cascade connection using the S-8225A Series, it is also possible to protect 6-serial or more cells lithium-ion rechargeable

battery pack.

 Features

• High-accuracy voltage detection function for each cell

Overcharge detection voltage n (n = 1 to 5)

3.5 V to 4.4 V (50 mV step)

Accuracy 20 mV (Ta = +25°C), 30 mV (Ta = 0°C to +60°C)

Overcharge release voltage n (n = 1 to 5)

Overdischarge detection voltage n (n = 1 to 5)

Overdischarge release voltage n (n = 1 to 5)

3.3 V to 4.4 V^*1

2.0 V to 3.2 V (100 mV step)

2.1 V to 3.4 V^*2

Accuracy 50 mV

Accuracy 80 mV

Accuracy 100 mV

• Overcharge detection delay time and overdischarge detection delay time can be set by external capacitor.

• Switchable between 3-serial to 5-serial cell by using the SEL1 pin and the SEL2 pin

• Cascade connection is available.

• The CO pin and the DO pin are controlled by the CTLC pin and the CTLD pin, respectively.

• Output voltage of the CO pin and the DO pin is limited to 12 V max.

• High-withstand voltage

Absolute maximum rating: 28 V

• Wide operation voltage range

• Wide operation temperature range

• Low current consumption

4 V to 26 V

Ta = −40°C to +85°C

During operation (V1 = V2 = V3 = V4 = V5 = 3.4 V)

22 μA max. (Ta = +25°C)

During power-down (V1 = V2 = V3 = V4 = V5 = 1.6 V) 4.5 μA max. (Ta = +25°C)

• Lead-free (Sn 100%), halogen-free

*1. Overcharge hysteresis voltage n (n = 1 to 5) is selectable in 0 V, or in 0.1 V to 0.4 V in 50 mV step.

(Overcharge hysteresis voltage = Overcharge detection voltage − Overcharge release voltage)

*2. Overdischarge hysteresis voltage n (n = 1 to 5) is selectable in 0 V to 0.7 V in 100 mV step.

(Overdischarge hysteresis voltage = Overdischarge release voltage − Overdischarge detection voltage)

 Application

• Lithium-ion rechargeable battery pack

 Package

• 16-Pin TSSOP
