The DS2775–DS2778 report available capacity for rechargeable lithium-ion (Li+) and Li+ polymer (Li-Poly) batteries in mAh and as a percentage of full. Safe operation is ensured by the integrated Li+ protector. The DS2776/DS2778 support SHA-1-based challengeresponse authentication in addition to all other DS2775/ DS2777 features. Precision measurements of vol.
Precision measurements of voltage, temperature, and current, along with a cell characteristics table and application parameters, are used for capacity estimation calculations. The capacity registers report a conservative estimate of the amount of charge that can be removed given the current temperature, discharge rate, stored charge, and application parameters. The DS2775
–DS2778 operate from +4.0V to +9.2V for direct integration into battery packs with two Li+ or LiPoly cells. In addition to nonvolatile storage for cell compensation and application parameters, the DS2775
–DS2778 offer 16 bytes.
