It integrates over-temperature and short-circuit fault protection, making it a self-contained charge controller for NiCd packs in commercial-temperature equipment. The 8-SOIC footprint keeps the board area small, and the surface-mount package suits automated assembly lines. ## Temperature range and environment — indoor only Rated for 0°C to 70°C ambient, this part is intended for indoor equipment where the ambient stays within that range. ## Fault protection scope — covers the basics Over-temperature and short-circuit protection are included, which handle the two most common failure modes in a battery charger: a thermal runaway condition or a dead short on the output. There is no reverse-battery or reverse-current protection on this device, so the design must ensure the pack is inserted with correct polarity and that no back-feeding path exists from the battery to the charger when input power is removed.","metaTitle":"LTC1559CS8-5#PBF NiCd Battery Power Management IC, 8-SOIC","metaDescription":"LTC1559CS8-5#PBF power management IC for single-cell Nickel Cadmium batteries.
