SAN JOSE, Calif., March 30, 2017 /PRNewswire/ -- Developers of
portable devices now have an easier way to design in the most
accurate and low power host-side battery gauges with the
MAX17055 ModelGauge™ m5 from Maxim Integrated Products, Inc.
(NASDAQ: MXIM).

Traditionally, fuel gauges required extensive characterization
of each battery type, used in specific applications, for attaining
good performance. This meant the customer had to perform
complicated battery characterization, adding weeks of time and
resources to the design cycle. With the ModelGauge m5 EZ
configuration of the MAX17055, battery characterization requirement
is eliminated, shortening the customer's time to market.
One of the main benefits of a fuel gauge is that the system
designer can use it to decide when to shut down the device when the
battery gets low. If the fuel gauge overestimates the battery life,
the shutdown might not happen before the voltage falls below the
minimum operating point, resulting in an unexpected crash.
Alternately, if the designer shuts down the system prematurely,
then the run-time becomes shorter, which is highly undesirable for
the user. By offering the industry's most accurate fuel gauge —
within 1% state of charge (SOC) error for most cases — the MAX17055
allows the designer to plan for a shutdown that maximizes the
device run-time.
The MAX17055 draws the industry's lowest quiescent current —
just 7µA in the low power operating mode. It is available in a
1.4mm x 1.5mm WLP for space constrained applications. Unlike other
gas gauges, the MAX17055 does not have a minimum battery size
limit, making it ideal for wearables, smartwatches, smartphones,
health and fitness monitors, body cameras, portable medical
devices, hearables, drones, virtual reality gear, and USB Type-C™
portable devices.
Key Advantages
- Highest accuracy: Within 1% SOC error in most scenarios
for maximum run-time
- Lowest quiescent current: 18/7µA low-power operation
prevents excessive energy loss
- Easy to design-in: No battery characterization or
calibration required with EZ configuration
- Enhanced user experience: Easy to use and accurate
time-to-empty and time-to-full information
Commentary
- "Having shipped more than one billion fuel gauge devices, Maxim
is continuously innovating to empower our customers to get the most
energy from their batteries," said Bakul
Damle, Mobile Power Business Management Director at Maxim
Integrated. "Why get caught with bad battery management? Eliminate
the risk by using the MAX17055, a host-side fuel gauge you can
trust."
