BQ24074RGTR in TI BQ24xxx / BQ25xxx Battery Charge Family
The BQ24074 series by Texas Instruments is a collection of highly integrated Li-Ion linear chargers and system power-path management ICs. Designed for space-constrained portable applications, these devices allow for simultaneous system powering and battery charging from either a USB port or an AC adapter. The architecture focuses on autonomous power source selection and dynamic power path management, ensuring the system remains operational even with a deeply discharged or missing battery pack.
Variants in This Sub-Family
Variants within the BQ2407x family primarily differ in their default safety timer durations, termination settings, and SYSOFF functionality. For example, while the BQ24074 includes a 1.5A charging capability and specific voltage thresholds, sibling parts like the BQ24075 or BQ24079 may offer different battery regulation voltages or integrated thermal foldback behaviors tailored for specific chemical safety profiles or different thermal management constraints in compact enclosures.
