Texas Instruments  BQ27750DRZT

The Texas Instruments bq27750 Impedance Track™ Gas Gaugeand Protection Solution is a highly integrated, accurate 1-series cell gas gauge and protectionsolution.

The bq27750 device provides a fully integrated pack-based solution with a flashprogrammable custom reduced instruction-set CPU (RISC), safety protection, and authentication for1-series cell Li-Ion and Li-Polymer battery packs.

The bq27750 gas gauge communicates via an I2C-compatibleinterface and combines an ultra-low-power, high-speed TI bqBMP processor, high-accuracy analogmeasurement 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-performancebattery management solution.
