MAX17048G+T10

MAX17048G+T10 is a 3μA 1-cell fuel gauge with ModelGauge. It is a tiny IC, micropower current fuel gauge for lithium-ion (Li+) batteries in handheld and portable equipment. The MAX17048 operates with a single lithium cell. The IC uses the sophisticated Li+ battery-modelling algorithm ModelGauge™ to track the battery's relative state-of-charge (SOC) continuously over widely varying charge and discharge conditions. Temperature compensation is implemented using the system microcontroller. The IC automatically detects when the battery enters a low-current state and enters low-power 3µA hibernate mode, while still providing accurate fuel gauging. The application includes smartphones, tablets, smartwatches, wearables, Bluetooth headsets, health and fitness monitors, digital still, video, and action cameras, medical devices, handheld computers and terminals, wireless speakers, home and building automation, and sensors.

• Precision ±7.5mV/cell voltage measurement
• Provides accurate state-of-charge, compensates for temperature/load variation
• Does not accumulate errors, unlike coulomb counters, eliminates learning and current-sense resistor
• Supply current is 3µA typ (Hibernate mode, reset comparator disabled (VRESET.Dis = 1, TA = +25°C))
• Fuel gauges in hibernate mode, automatically enters and exits hibernate mode
• Reports charge and discharge rate, supply voltage range from 2.5 to 4.5V (TA= -20°C to +70°C)
• Best of 16 samples to estimate initial SOC
• Low SOC, 1% Change in SOC, battery undervoltage/overvoltage, VRESET alert, I²C interface
• 8 TDFN-EP package
• Operating temperature range from -40°C to +85°C
