Seiko Instruments Inc. (SII) announced the release of the S-8240 Series, 1-cell lithium-ion battery protection IC available in a 1.2 x 1.2 x 0.4 mm package. The S-8240 features an industry leading ±5mV charge and discharge overcurrent detection voltage accuracy and ultra-low 1.5µA current consumption. The S-8240 has been optimized for use in smart phones, wearable devices, and other battery-operated portable device designs. Lithium-ion battery protection ICs protect lithium-ion batteries from failure including over-charging, over-discharging, over-current and short-circuiting.
Leveraging SII’s HSNT-6 (1212) package, the S-8240 requires only half the footprint of SII’s conventional SNT-6A packaged ICs and is ultra-light weight at 1.6 mg. These key features help to save space and meet the designer’s needs for creating small, thin, and lightweight battery packs. The high-precision ±5mV charge and discharge overcurrent detection voltage accuracy helps allow for higher reliability and safety of lithium-ion battery packs when compared to those with typical industry accuracy of ±10mV to ±15mV. The 1.5µA current consumption during operation helps to prolong battery runtime when compared to typical battery protection IC current consumption of nearly twice this amount.
