BQ24075RGTR in TI BQ24xxx / BQ25xxx Battery Charge Family
The BQ24075RGTR is a highly integrated lithium-ion linear battery charger and system power path management IC manufactured by Texas Instruments. It is designed for space-constrained portable applications, enabling the device to power the system while simultaneously charging the battery. The family features dynamic power path management (DPPM), which automatically reduces the charge current when the system load increases to prevent crashing the input source, making it ideal for USB-powered devices.
Variants in This Sub-Family
Variants within the BQ24x series primarily differ in their output voltage regulation, charging current limits, and specific safety logic. For example, some versions offer different fixed output voltages or varied behavior for the SYSOFF and EN1/EN2 pins to accommodate diverse processor logic levels. The BQ24075 specifically includes a 4.2V battery regulation voltage and integrated thermal protection, distinguishing it from lower-current variants or those with different termination thresholds.
