MAX17435 datasheet

 

Description

The MAX17435, MAX17535 integrated multichemistry battery-charger ICs simplify construction of accurate and efficient chargers. The device provide SMBusK-programmable charge current, charge voltage, input current limit, relearn voltage, and digital readback of the IINP voltage. The IC
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 device 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 10mIsense resistors.
