BQ25120AEVM in TI BQ24xxx / BQ25xxx Battery Charge Family
The BQ25120AEVM is a comprehensive evaluation module from Texas Instruments designed for the BQ25120A, an ultra-low-power battery management solution. This IC family integrates a linear charger, a regulated output, a load switch, manual reset with a timer, and battery voltage monitoring into a single chip. It is specifically engineered to maximize battery life in compact designs by maintaining a 700nA quiescent current, making it a critical component for small-scale energy-harvesting and wearable systems.
Variants in This Sub-Family
Variants within the BQ2512x series primarily differ in their default factory-programmed settings such as pre-set buck converter voltages, I2C addresses, and manual reset timer durations. Some versions offer specific optimizations for different battery chemistries or maximum charge rates, though most maintain the same pinout and 2.5mm x 2.5mm WCSP packaging to allow for layout reuse across different hardware revisions.
