Product details

The BQ24195RGER is a Texas Instruments single-cell Lithium Ion/Polymer battery charger IC delivering up to 4.5 A of programmable charge current. The I²C interface lets a host microcontroller set charge parameters, read status, and enable fault recovery without external trim resistors. Input voltage tolerance to 17 V covers USB VBUS, 5 V adapters, and 12 V wall warts, with integrated over-voltage protection that clamps transients without an external TVS diode.

Industrial temperature and package for embedded designs

Fault protection covers over-current, over-temperature, and over-voltage, reducing the need for discrete supervisory circuits and simplifying the BOM for space-constrained battery-powered products.

Frequently asked questions

Is BQ24195RGER compatible with 2-cell Li-ion batteries?

No—the BQ24195RGER is designed for single-cell (1S) Li-ion or Li-polymer batteries with a 4.2 V charge termination voltage. For 2-cell applications, consider a charger with a higher cell count rating.

What is the charge current range for BQ24195RGER?

The charge current is constant and programmable up to 4.5 A maximum. The actual range depends on the I²C register settings and the thermal capability of the PCB layout.

What is the difference between BQ24195RGER and BQ24195?

The base product number is BQ24195. The 'RGER' suffix indicates the specific package and reel configuration—24-VQFN (4x4 mm) on Tape & Reel. The electrical characteristics are identical; the suffix only affects the ordering and packaging format.

Does BQ24195RGER support USB BC1.2?

The evidence does not list USB BC1.2 support. The I²C interface allows a host to implement BC1.2 detection externally, but the charger itself does not include a BC1.2 detection block.
