• Manufacturer Part Number: s-8232nbft-t2-g
• Description: Battery Protection Ic For 2-serial-cell Pack
• Manufacturer: Seiko Instruments Inc.

*1. Auxiliary overcharge detection voltage is equal to the overcharge detection voltage times 1.11 for the
*2. Temperature coefficient 1 for detection voltage should be applied to overcharge detection voltage,
*3. Temperature coefficient 2 for detection voltage should be applied to overcurrent detection voltage.
*4. Since products are not screened at high and low temperature, the specification for this temperature range is
*5. The DO and CO pin logic are established at the operating voltage.
