© SII Semiconductor Corporation, 2012-2017
The S-8213 Series is used for secondary protection of lithium-ion rechargeable batteries, and incorporates a high-accuracy
voltage detection circuit and a delay circuit. Short-circuits between VC3 to VSS accommodate serial connection of two cells or
three cells.
