DS2784 Datasheet | Maxim Integrated

.. 1-Cell Stand-Alone Fuel Gauge IC with Li+ Protector and SHA-1 Authentication .maxim-ic. GENERAL DESCRIPTION The DS2784 operates from 2.5V to 4.6V for integration in battery packs using a single lithium-ion (Li+) or Li+ polymer cell. Available capacity is reported in mAh and as a percentage. Safe operation is ensured with the included Li+ protection function and SHA-1-based challenge-response authentication. Precision measurements of voltage, temperature, and current, along with cell characteristics and application parameters are used to estimate capacity. The available capacity registers report a conservative estimate of the amount of charge that can be...
