Description
General part information
BQ27Z746 Series
The Texas Instruments BQ27Z746 Impedance Track™ gas gauge solution is a highly integrated, accurate 1-series cell gas gauge and protection solution.
The BQ27Z746 device provides a fully integrated pack-based solution with a flash programmable custom reduced instruction-set CPU (RISC), safety protection, differential battery sensing analog output, and authentication for 1-series cell Li-ion and Li-polymer battery packs.
The BQ27Z746 gas gauge communicates through an I2C compatible interface and combines an ultra-low power TI BQBMP processor, high accuracy analog measurement capabilities, integrated flash memory, N-CH high-side FET drive, and a SHA-2 Authentication transform responder into a complete, high-performance battery management solution.
