Description

The Texas Instruments bq27750 Impedance Track™ device is a highly integrated, accurate 1-series cell gas gauge and protection solution. The bq27750 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 bq27750 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.
