BQ24195LRGER in TI BQ24xxx / BQ25xxx Battery Charge Family
The BQ24195LRGER belongs to the Texas Instruments BQ2419x family of highly integrated switch-mode battery charge management and system power path management devices. Designed for single-cell Li-Ion and Li-polymer batteries, it supports high-current charging up to 4.5A and power path operation. It features an I2C serial interface for flexible parameter setting, making it a standard choice for portable devices requiring fast charging, USB On-The-Go (OTG) support, and efficient power distribution between the battery and system rail.
Variants in This Sub-Family
Variants within the BQ2419x series primarily differ in their default charging currents, input voltage limits, and USB OTG output capabilities. For instance, the BQ24195 is optimized for 2.1A OTG boost output, while other family members like the BQ24190 or BQ24192 may offer different pin-strapping options for autonomous mode or varying shipping mode entry behaviors to suit specific low-power standby requirements or different system-level I2C controller priorities.
