Charging current is constant and programmable via the I²C interface — no external sense resistor divider needed for current setting. Fault protection is on-chip: overcurrent, overvoltage, and short-circuit detection are included, reducing the external component count for a production BOM. ## I²C bus sets the charge profile — firmware owns the loop Charge current and voltage are written over the I²C bus, so the system microcontroller or embedded controller manages the charging algorithm. No potentiometer or resistor-divider network on the charge-voltage feedback pin — the firmware controls the taper and termination. For dual-sourcing, evaluate the BQ24725 family pin-compatible variants; confirm the I²C register map and protection thresholds match your firmware driver.","metaTitle":"BQ24725RGRR I²C Li-Ion Battery Charger, 24V Input, 2–4 Cells","metaDescription":"Texas Instruments BQ24725RGRR — I²C-controlled Li-Ion charger IC, 24V max supply, 2–4 cells, integrated OVP/OCP/SCP.
