The device uses the Intel SMBus to control the charge voltage and charge current.
It charges one to four lithium-ion (Li+) cells in series, at charge currents greater than 2A.
The MAX8713 provides 0.5% accurate battery-voltage regulation, which increases battery capacity and minimises charging time.
The charge-current regulation accuracy is 5% and the charge-current sense amplifier has low offset error, allowing the use of small-value sense resistors.
The MAX8713 is packaged in a space-saving 28-pin QFN (4 x 4mm) and is specified for the industrial temperature range (-40 to +85C).
Prices start at $5.04 (1000-up, FOB USA).
