KIT ATION EVALU ILABLE AVA
SMBus Level 2 Battery Charger with Remote Sense
General Description
The MAX8731A is an SMBusTM programmable multichemistry battery charger.
The MAX8731A uses a minimal command set to easily program the charge voltage, charge current, and adapter current limit. The MAX8731A charges one to four Li+ series cells and delivers up to 8A charge current. The MAX8731A drives n-channel MOSFETs for improved efficiency and reduced cost. Low-offset current-sense amplifiers provide high accuracy with 10m sense resistors. The MAX8731A current-sense amplifiers provide high accuracy (3% at 3.5A) and also provide fast cycle-bycycle current-mode control to protect against battery short circuit and system load transients. The charger employs dual remote sense, which reduces charge time by measuring the feedback voltage directly at the battery, improving accuracy of initial transition into constant-voltage mode. The MAX8731A provides 0.5% battery voltage ac
