Product details

3A charge current and I²C programmability

The BQ24298RTWR is a single-cell Li-Ion/Polymer charger IC delivering up to 3A programmable charge current via I²C interface — the 3A ceiling sets the minimum charge time for a 3000 mAh pack at roughly one hour, assuming the input supply and thermal budget support it. Constant-current charging is programmable through the I²C bus, which also provides status monitoring and termination control — the host microcontroller reads the charge state without a separate ADC pin.

Fault protection and supply range

Integrated overcurrent, overtemperature, and overvoltage protection means the charger handles input transients and battery faults without external comparators — the 6.2V max supply voltage gives headroom for 5V USB adapters and 5V regulated rails.

Surface-mount assembly with Tape & Reel or Cut Tape packaging — the 24-WFQFN footprint is standard for QFN reflow profiles; no special stencil aperture beyond the datasheet land pattern.

ROHS3 compliant — the part meets the latest EU restriction directive; no exemption declarations needed for EU-market equipment.

Frequently asked questions

How do I get current pricing and availability for BQ24298RTWR?

The part is sourced through independent distribution channels with full traceability.

What is BQ24298RTWR's listed interface?

The BQ24298RTWR uses an I²C interface for charge current programming, termination voltage selection, and status monitoring — the host microcontroller communicates over the standard two-wire bus without additional level shifting at 1.8V or 3.3V logic.

What compliance documentation does Texas Instruments provide for BQ24298RTWR?

Texas Instruments provides ROHS3 compliance certification for the BQ24298RTWR. The part is also covered by the standard TI datasheet and application notes — no separate UL or IEC certification documents are listed on this record.
