BQ07A BQ24707A BQ 24707A Battery Charging Controller IC
Reviews
Category: BQ ICs
Description
The BQ24707A (commonly marked as BQ07A) is a high-efficiency SMBus-controlled battery charger controller designed for 1–4 series Li-Ion and Li-Polymer cells. Developed by Texas Instruments, it operates in a synchronous step-down (buck) configuration and provides digitally programmable charging voltage and current for optimal control.
This IC is widely used in notebooks, ultrabooks, and embedded charging systems due to its Dynamic Power Management (DPM) capability, which allows the system to continue operating even when the adapter is current-limited. Integrated MOSFET drivers and advanced safety protections make the BQ24707A a reliable choice for smart battery applications.
