S-8204BAG-TCT1U

Battery Management Overview

The S-8204BAG-TCT1U is a battery protection IC designed for lithium-ion or lithium-polymer secondary battery packs consisting of three to four cells in series. It integrates overcharge protection, overdischarge protection, and overcurrent protection functions within a single chip. The device operates with a supply voltage range of 2 V to 22 V and features a low power consumption mode with a standby current of 15 µA typical. It utilizes an external detection circuit composed of two N-channel MOSFETs to control the charging and discharging paths. The component is housed in a TSSOP-B16 package suitable for surface mount technology.
