The DS2784G+T&R from Analog Devices (Maxim Integrated) is a versatile 1-cell fuel gauge IC for lithium-ion and Li-polymer battery packs, operating within a voltage range of 2.5V to 4.6V. It offers precise measurement of voltage, temperature, and current to estimate available capacity in mAh and percentage.
Key features include Li+ safety circuitry with overvoltage, undervoltage, overcurrent, and short-circuit protection, along with programmable safety thresholds. The IC supports SHA-1 based challenge-response authentication for secure pack operation. Communication is handled via a 1-Wire interface, supporting speeds of 16kbps or 143kbps.
This device is suitable for applications such as health and fitness monitors, digital cameras, medical devices, handheld computers, and power tools. It is available in a 14-TDFN package suitable for surface mounting, embedding easily into battery packs.
The DS2784G+T&R also includes nonvolatile storage for cell compensation and application parameters, with 16 bytes of EEPROM available for user data, facilitating lot tracking and usage statistics.
