BQ24074 in TI BQ24xxx / BQ25xxx Battery Charge Family
The BQ24074 series by Texas Instruments is a highly integrated family of standalone Li-Ion linear chargers with integrated Dynamic Power-Path Management (DPPM). Designed for single-cell lithium-ion and lithium-polymer batteries, these ICs balance the power delivered between the system load and the battery charging circuit. This architecture allows the system to remain operational even with a deeply discharged or missing battery, making it a reliable choice for portable electronic devices requiring robust power handling and safety features.
Variants in This Sub-Family
Variants within the BQ24x series primarily differ in their fixed output voltages, overvoltage protection (OVP) thresholds, and logic pin configurations. For example, while the BQ24074 features a 4.4V regulated output, others like the BQ24072 or BQ24075 offer different voltage rails or specific behaviors for the CE and EN pins. Some members also vary in their handling of the SYSOFF function or the presence of a dedicated power-good (PG) status indicator.
