Highly integrated battery gas gauge and protection solution for Li-Ion battery packs

The Texas Instruments bq27750 Impedance Track Gas Gauge and Protection Solution is a highly integrated, accurate 1-series cell gas gauge and protection solution. The device provides a fully integrated pack-based solution with a flash programmable custom reduced instruction-set CPU (RISC), safety protection, and authentication for 1-series cell Li-Ion and Li-Polymer battery packs. The gas gauge communicates via an I2C-compatible interface and combines an ultra-low-power, high-speed TI bqBMP processor, high-accuracy analog measurement capabilities, integrated flash memory, an array of peripheral and communication ports, an N-CH FET drive, and a SHA-1 Authentication transform responder into a complete, high-performance battery management solution.
