BQ24074RGTRG4 in TI BQ24xxx / BQ25xxx Battery Charge Family
The BQ24074RGTRG4 series, manufactured by Texas Instruments, belongs to the BQ2407x family of highly integrated Li-ion linear chargers and system power path management devices. Designed specifically for space-constrained portable applications, these ICs operate from either a USB port or an AC adapter and support charge currents up to 1.5A. The power-path management allows the system to power up instantly from an external source even when the battery is deeply discharged or absent.
Variants in This Sub-Family
Variants within the BQ2407x sub-family primarily differ in their specific safety timer settings and the behavior of the SYSOFF and EN1/EN2 pins. While the BQ24074 features a standard charging profile, related versions like the BQ24075 or BQ24079 may offer different battery regulation voltages or variations in the input current limit default states to better suit specific USB or proprietary adapter requirements.
