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.
