com KIT ATION EVALU E L B A AVAIL Simplified Multichemistry SMBus Battery Charger General Description Features ♦ Over 2A Charge Current ♦ Intel SMBus 2-Wire Serial Interface ♦ ±0.
6% Charge Voltage Accuracy ♦ 11-Bit Charge Voltage Resolution ♦ 6-Bit Charge Current Resolution ♦ Adjustable Switching Frequency ♦ +8V to +28V Input Voltage Range ♦ Cycle-By-Cycle Current Limit ♦ Charges Any Battery Chemistry (Li+, NiCd, NiMH, Lead Acid, etc.
) ♦ Small 24-Pin TQFN MAX8713 The MAX8713 multichemistry battery charger simplifies construction of smart chargers with a minimum number of external components.
It uses the Intel System 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.
