The operating temperature range of -40°C to 85°C (TA) covers industrial and outdoor portable equipment but stops short of automotive under-hood requirements — for that, the BQ79612PAPRQ1 carries a -40°C to 125°C range and AEC-Q100 qualification.","metaTitle":"BQ27542DRZT-G1 Impedance Track Battery Monitor, I²C/HDQ","metaDescription":"TI BQ27542DRZT-G1 single-cell Li-ion battery fuel gauge with Impedance Track algorithm.
