Secondary lithium ion battery protection chip in smallest package
The S-8223A/B/C/D Series has a current consumption of 0.25 μA, a quarter of existing products.
The devices are aimed at protecting lithium-ion batteries in laptop computers and other portable devices from overcharging, overdischarging, overcurrent and short circuits. The use of a secondary protection IC like the S-8223A/B/C/D Series is especially critical in cases of overcharge conditions which may result in heating and ignition of the lithium-ion batteries.
The S-8223 Series also has the industry’s highest class accuracy in overcharge detection voltage at ±20 mV. This provides enhanced safety monitoring of lithium-ion rechargeable batteries. The S-8223B/D Series has a gate connection terminal of the charge control FET equipped with an output voltage control circuit, meaning the series is also compatible with a FET at a gate-source withstanding voltage of 12 volts.
