Product Overview

The MAX8731AETI+ is an SMBus level-2 battery charger with remote sense in 28 pin TQFN package. It uses a minimal command set to easily program the charge voltage, charge current and adapter current limit. The device charges one to four Li+ series cells and delivers up to 8A charge current. It drives n-channel MOSFETs for improved efficiency and reduced cost. Low-offset current-sense amplifiers provide high accuracy with 10mR sense resistors. The charger employs dual remote sense which reduces charge time by measuring the feedback voltage directly at the batter and improves accuracy of initial transition in constant-voltage mode.
