The S-19161B Series from ABLIC are Battery Protection ICs that are designed for 1-cell lithium-ion and lithium polymer rechargeable battery packs. They require an input voltage of up to 28 V. These ICs ensure the safety and longevity of the battery by providing precise protection against overcharging, over-discharging, and overcurrent conditions. They have high-accuracy voltage detection circuits with customizable detection and release voltages for over-charge, over-discharge, and over-current scenarios. These ICs include built-in delay circuits, eliminating the need for external capacitors, and offer discharge overcurrent control, 0 V battery charging capability, and a power-down function to conserve energy. They are available in a surface-mount package that measures 2.9 x 2.8 x 1.35 mm.
