FOR AUTOMOTIVE BATTERY PROTECTION IC
FOR 3-SERIAL TO 5-SERIAL CELL PACK (SECONDARY PROTECTION)
© SII Semiconductor Corporation, 2013-2016
Rev.1.7_00
The S-8235A Series, for automotive use, is utilized for secondary protection of lithium-ion rechargeable batteries, and
incorporates high-accuracy voltage detection circuits and delay circuits. Short-circuiting between cells makes it possible for
serial connection of 3-cell to 5-cell. By connecting in cascade, the S-8235A Series protects 6-serial or more cells lithium-ion
rechargeable battery pack.
The S-8235A Series performs a self-test operation to confirm overcharge detection.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the
purpose, contact to SII Semiconductor Corporation is indispensable.
