Description

This is High-Frequency Low-Cost SMBus Chargers. MAX17435, MAX17535 19-4817; Rev 1; 9, 10 EVAALVUAAILTAIOBNLEKIT High-Frequency, Low-Cost SMBus Chargers General Description The MAX17435, MAX17535 integrated multichemistry battery-charger ICs simplify construction of accurate and efficient chargers. The MAX17435, MAX17535 provide SMBusK-programmable charge current, charge voltage, input current limit, relearn voltage, and digital readback of the IINP voltage. The 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 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 10mI sense resistors. The MAX17435, MAX17535 fixed-inductor ripple architecture significantly reduces component size and circuit cost. The MAX17435, MAX17.
