The I²C interface lets the host controller adjust the charge current, termination threshold, safety timer, and battery regulation voltage on the fly — useful when the same PCB must support different cell capacities or chemistries. ## Protection and temperature range On-chip fault protection covers over-current, over-voltage, and over-temperature conditions — the part shuts down before the external MOSFET or inductor sees stress. ## Package and footprint reality Housed in a 24-VFQFN with exposed pad (4x4 mm body). The supplier device package is 24-VQFN (4x4), which is the same mechanical outline; the 'R' suffix in the order code indicates tape-and-reel or cut-tape delivery.","metaTitle":"BQ24296MRGER I²C Li-Ion Charger, 3A, 24-VQFN","metaDescription":"TI BQ24296MRGER single-cell Li-Ion/Li-Pol charger with I²C interface, 3A max charge current, fault protection, -40°C to 85°C.
