S-8225B Datasheet, Specifications, Parts list and Support

The S-8225B Series includes a voltage detection circuit with high accuracy and a delay circuit, 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 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): 3.3 V to 4.4 V^*1 , Accuracy ±50 mV; Overdischarge detection voltage n (n = 1 to 5): 2.2 V to 3.2 V (100 mV step) , Accuracy ±80 mV; Overdischarge release voltage n (n = 1 to 5): 2.2 V to 3.4 V^*2 , 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 operating voltage range: 4 V to 26 V
Wide operating temperature range: Ta = -40°C to +85°C
Low current consumption: During operation (V1 = V2 = V3 = V4 = V5 = 3.4 V) : 20 µA max. (Ta = +25°C); During power-down (V1 = V2 = V3 = V4 = V5 = 1.6 V): 3.0 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, or in 0.2 V to 0.7 V in 100 mV step.
(Overdischarge hysteresis voltage = Overdischarge release voltage - Overdischarge detection voltage)

Parts List

U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
These descriptions may be different from the actual product name and parameter.
Please confirm the product name and specifications with the data sheet again.
