Charge current is constant and programmable via the I²C interface — the host microcontroller sets the charge current, charge voltage, and input current limit by writing to the internal registers, eliminating the need for external resistor dividers for charge parameter adjustment. The 24V maximum supply voltage covers the common 19V to 20V notebook adapter rails and allows headroom for the buck converter to regulate the charge voltage. ## Fault protection and thermal range Integrated fault protection monitors for over-current, over-voltage, and short-circuit conditions on the battery or adapter input, reducing external supervisory circuitry.","metaTitle":"BQ24725RGRT Texas Instruments Li-Ion Battery Charger IC, I²C","metaDescription":"Texas Instruments BQ24725RGRT Li-Ion battery charger IC, 2-4 cells, I²C interface, 20-VQFN.
