ABLIC Inc. Battery Management S-8204AAJ-TCT1U

The S-8204AAJ-TCT1U is a battery protection IC designed for use with 3-series or 4-series lithium-ion rechargeable battery packs. It features high-accuracy voltage detection circuits for overcharge and overdischarge conditions, with detection voltages adjustable from 3.8 V to 4.6 V for overcharge and from 2.0 V to 3.0 V for overdischarge. The device supports cascade connections, allowing for protection of larger battery packs with up to 6-series cells. This IC includes a discharge overcurrent detection function with three detection levels and a charge overcurrent detection function. It operates within a voltage range of 2 V to 22 V and has a wide temperature range of -40¬8C to +85¬8C. The S-8204AAJ-TCT1U is packaged in a 16-pin TSSOP and is characterized by low current consumption, with a maximum of 33 ¬µA during operation and 0.1 ¬µA during power-down. The product is lead-free and halogen-free, making it suitable for environmentally conscious applications. It is important to note that the overcharge and overdischarge hysteresis voltages are selectable, providing flexibility in design. This IC is ideal for engineers looking for a reliable solution for battery management in lithium-ion applications.
