Maxim Releases Latest MAX17055 ModelGauge m5 Fuel Gauge

Maxim's latest MAX17055 ModelGaugeTM m5 fuel gauges make it easier for portable device developers to design the highest precision, lowest power host-side battery fuel gauges.

In the conventional method, the fuel gauge needs to perform a large number of characterizations for each battery model according to a specific application, thereby obtaining excellent performance. This means customers need to add weeks and resources to the design cycle to implement complex battery characterization. The MAX17055's ModelGauge m5 EZ configuration eliminates battery dependence and dramatically reduces time-to-market for customers.

One of the main advantages of the fuel gauge is that it helps system developers determine when to turn off the device when the battery is low. If the fuel gauge is too high or low to estimate battery life, when the voltage drops below the operating voltage of the device, the device may not shut down properly, resulting in an unexpected failure; if the designer shuts down the system too early, it will reduce the uptime of the device. This is very undesirable for the user. By providing the most accurate fuel gauge – in most cases less than 1% of the state of charge (SOC) indication error, the MAX17055 allows designers to develop a shutdown schedule based on the longest equipment uptime.

The MAX17055 achieves the industry's lowest quiescent current – ​​consuming only 7μA in low-power mode. For space-constrained applications, it can support 1.4mm x 1.5mm WLP packages. Unlike other fuel gauges, the MAX17055 has no minimum battery size and is ideal for wearables, smart watches, smartphones, health and fitness monitoring, portable cameras, portable medical devices, smart earwear, drones, VR devices and USB Type-CTM portable devices.
