MAX17201G+T

MAX17201G+T is a stand-alone ModelGauge m5 fuel gauge with SHA-256 authentication. It is an ultra-low power stand-alone fuel gauge IC that implements the ModelGauge™ m5 algorithm without requiring host interaction for configuration. It incorporates a unique 64-bit ID. The IC provides precision measurements of current, voltage, and temperature. The temperature of the battery pack is measured using an internal temperature measurement and up to two external thermistors supported by ratiometric measurements on auxiliary inputs. The ModelGauge™ m5 algorithm combines the short-term accuracy and linearity of a coulomb counter with the long-term stability of a voltage-based fuel gauge, along with temperature compensation to provide industry-leading fuel gauge accuracy. Typical applications are smartphones and tablets, portable game players, e-readers, digital still and video cameras, handheld computers and terminals, portable medical equipment, and handheld radios.

• Eliminates error when approaching empty voltage, eliminates coulomb-counter drift
• Current, temperature, and age compensated, does not require empty, full, or idle states
• Non-volatile memory for stand-alone operation, learned parameters and history logging
• Precision measurement system, no calibration required
• Time-to-Empty and Time-to-Full estimation, multiple series cell pack operation
• Temperature measurement, die temperature, up to two external thermistors
• High-speed overcurrent comparators, predicts remaining capacity under theoretical load
• SHA-256 authentication, SBS 1.1 compatible register set
• 14-pin TDFN-EP package
• Temperature rating range from -40°C to +85°C
