max17035, max17435, max17535 高频、低成本smbus电池充电器
概述
the max17035/max17435/max17535 integrated multichemistry battery chargers ic simplify construction of accurate and efficient chargers. the max17035/max17435/max17535 provide smbus™-programmable charge current, charge voltage, input current limit, relearn voltage, and digital readback of the iinp voltage. the max17035/ max17435/max17535 utilize a charge pump to control the adapter selection n-channel mosfets when the adapter is present. when the adapter is absent, the charge pump is shut down and a p-channel mosfet selects the battery.
the max17035/max17435/max17535 provide up to 7a of charge current to 2, 3, or 4 lithium-ion (li+) cells in series. the charge current, and input current-limit sense amplifiers have low offset errors and can use 10mω sense resistors. the max17035/max17435/max17535 fixed-inductor ripple architecture significantly reduces component size and circuit cost.
the max17035/max17435/max17535 provide a digital output that indicates the presence of the adapter, an analog output that indicates the adapter or battery current, depending upon the presence or absence of the adapter, and a digital output that indicates when the adapter current exceeds a user-defined threshold.
the max17035 operates with a switching frequency of 1.2mhz. the max17435 switches at 850khz, and the max17535 switches at 500khz.
the max17035/max17435/max17535 are available in a small, 4mm x 4mm x 0.75mm 24-pin, lead-free qfn package. an evaluation kit is available.
