Analog Devices MAX17201/5 and MAX17211/5 Fuel Gauge ICs | DigiKey Daily

Analog Devices' MAX17201/5 and MAX17211/5 are ultra-low-power, stand-alone fuel gauge integrated circuits that implement the Analog Devices ModelGauge m5 algorithm without requiring host interaction for configuration. These ICs provide precision measurements of current, voltage, and temperature, and provide accurate estimation of time-to-empty and time-to-full. A Analog Devices 1-Wire® or 2-wire I2C interface provides access to data and control registers. To prevent battery-pack cloning, the ICs integrate SHA-256 authentication with a 160-bit secret key, incorporating a unique, 64-bit ID. These integrated circuits are ideal for handheld devices including smartphones, tablets, and cameras.
