MAX17040/MAX17041
Compact, Low-Cost 1S/2S Fuel Gauges
General Description
The MAX17040/MAX17041 are ultra-compact, low-cost,
host-side fuel-gauge systems for lithium-ion (Li+) batter-
ies in handheld and portable equipment. The MAX17040
is configured to operate with a single lithium cell and the
MAX17041 is configured for a dual-cell 2S pack.
The MAX17040/MAX17041 use a sophisticated Li+ bat-
tery-modeling scheme, called ModelGauge? to track
the battery’s relative state-of-charge (SOC) continuously
over a widely varying charge/discharge profile. Unlike
traditional fuel gauges, the ModelGauge algorithm elim-
inates the need for battery relearn cycles and an exter-
nal current-sense resistor. Temperature compensation
is possible in the application with minimal interaction
between a μC and the device.
A quick-start mode provides a good initial estimate of
the battery ’s SOC. This feature allows the IC to be
located on system side, reducing cost and supply
chain constraints on the battery. Measurement and esti-
mated capacity data sets are accessed through an I 2 C
interface. The MAX17040/MAX17041 are available in
either a 0.4mm pitch 9-bump UCSP? or 2mm x 3mm,
8-pin TDFN lead-free package.
