Product details

3 A charge current with I²C programmability

The Texas Instruments BQ24296MRGER is a single-cell Li-Ion/Li-Polymer battery charger that delivers a programmable constant charge current up to 3 A. 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.

Frequently asked questions

How do I program BQ24296MRGER via I²C?

The charger is controlled through an I²C-compatible interface. The host writes to the device's register map to set charge current, termination current, safety timer, and enable/disable charging. The datasheet provides the register addresses and bit-field definitions.
