BATTERY MONITORING IC
FOR 3-SERIAL TO 5-SERIAL CELL PACK
Rev.1.5_02
The S-8225B 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-8225B Series for 3-serial to 5-serial cell 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)
Overcharge release voltage n (n = 1 to 5)
Accuracy 20 mV (Ta = 25C), 30 mV (Ta = 0C to 60C)
3.3 V to 4.4 V*1
Accuracy 50 mV
Overdischarge detection voltage n (n = 1 to 5)
Overdischarge release voltage n (n = 1 to 5)
2.2 V to 3.2 V (100 mV step)
2.2 V to 3.4 V*2
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
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.
Output logic is selectable.
Active "H", active "L"
High-withstand voltage
Absolute maximum rating: 28 V
Wide operation voltage range
4 V to 26 V
Wide operation temperature range
Ta = 40C to 85C
Low current consumption
During operation (V1 = V2 = V3 = V4 = V5 = 3.4 V) 20 A max. (Ta = 25C)
During power-down (V1 = V2 = V3 = V4 = V5 = 1.6 V) 3.0 A max. (Ta = 25C)
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, or in 0.2 V to 0.7 V in 100 mV step.
(Overdischarge hysteresis voltage = Overdischarge release voltage Overdischarge detection voltage)
Application
