3 to 16 series Li-ion highly integrated battery fuel gauge, monitor and protector

The Texas Instruments BQ41Z90 is a fully integrated pack-based

battery pack manager solution, that provides a flash

programmable CPU, safety protection, and elliptical curve

cryptography (ECC) authentication for 3 to 16 cells in

series Li-ion, LiFeP4, NiMH, and Li-polymer battery

packs.

The BQ41Z90 battery pack

manager communicates through SMBus v3.2 or

I2C-compatible interfaces, and combines an

ultra-low-power, high-speed 32-bit processor, high-accuracy

analog measurement capabilities, integrated flash memory, an

array of peripheral IO, an NMOS protection FET drive, and a

SHA-1, SHA-2, or EC-KCDSA authentication responder into a

complete, high-performance battery management solution.
