BQ28Z610DRZR 编带

The Texas Instruments bq28z610 device is a highly integrated, accurate, 1-series to 2-series cell gas gauge and protection solution, enabling autonomous charger control and cell balancing.

The bq28z610 device enables autonomous charge control through Master Mode I2C broadcasts of charging current and voltage information, eliminating software overhead that is typically incurred by the system’s host controller.

The bq28z610 device provides a fully integrated pack-based solution with a flash programmable custom reduced instruction-set CPU RISC, safety protection, and authentication for 1- to 2-series cell Li-Ion and Li-Polymer battery packs.

The bq28z610 gas gauge communicates via an I2C compatible interface and combines an ultra-low-power, high-speed 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.

The bq28z610 device provides an array of battery and system safety functions, including overcurrent in discharge, short circuit in charge, and short circuit in discharge protection for the battery, as well as FET protection for the N-channel FETs, internal AFE watchdog, and cell balancing. Through firmware, the devices can provide a larger array of features including protection against overvoltage, undervoltage, overtemperature, and more.
