Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX8713 multichemistry battery charger simplifies construction of smart chargers with a minimum number of external components. It uses the Intel  ystem Management Bus (SMBus™) to control the charge voltage and charge current. High efficiency is achieved through the use of a constant off-time step-down topology with synchronous rectification.

The MAX8713 charges one to four lithium-ion (Li+) cells in series and delivers over 2A charge current-scalable with the sense resistor. The MAX8713 drives n-channel MOSFETs for improved efficiency and reduced cost. A low-offset charge-current-sense amplifier provides highaccuracy charge current with small sense resistors.

The MAX8713 is available in a space-saving 24-pin 4mm x 4mm thin QFN package and operates over the extended (-40°C to +85°C) temperature range. An evaluation kit is available to reduce design time.
