BQ24075RGTT in TI BQ24xxx / BQ25xxx Battery Charge Family
The BQ24075RGTT is a member of the Texas Instruments BQ24xxx series of integrated Li-Ion linear chargers and system power path management ICs. Designed for space-constrained portable applications, this family enables simultaneous battery charging and system power from an unregulated adapter or USB port. It features autonomous power path control, ensuring the system remains operational even with a deeply discharged or missing battery, while managing input current limits to prevent crashing the supply source.
Variants in This Sub-Family
Variants within the BQ2407x sub-family primarily differ in their SYSOFF functions, termination settings, and output voltage levels. For instance, the BQ24075 features a specific 5.5V SYSOFF function and fixed charging parameters, while the BQ24079 provides a lower regulated battery voltage. Engineers should choose specific part numbers based on the required battery chemistry termination voltage (4.2V vs 4.35V) and whether they need an integrated power-good (PG) status indicator.
