The MAX17435ETG+ is a high frequency, low-cost SMBus battery charger in 24 pin TQFN package. This device is an integrated multichemistry battery charger IC which simplifies construction of accurate and efficient chargers. It provide SMBus-programmable charge current, charge voltage, input current limit, relearn voltage and digital readback of the IINP voltage. The device charges 2, 3, or 4 lithium-ion (Li+) cells in series, charge current and input current-limit sense amplifiers have low offset errors, fixed-inductor ripple architecture significantly reduces component size and circuit cost.
