The BQ24166RGER is a Texas Instruments single-cell Li-Ion battery charger designed for USB-powered or adapter-powered portable devices. It delivers a programmable constant charge current up to 2.5 A (cite:) from a supply voltage up to 10 V (cite:). The charger integrates over-temperature and short-circuit fault protection (cite:), reducing external component count for a compact charging solution.
The maximum programmable charge current is 2.5 A (cite:). The actual current is set by an external resistor; the 2.5 A ceiling is the upper limit of the constant-current regulation loop.
No. The BQ24166RGER is designed for a single-cell Li-Ion battery (cite:) with a nominal pack voltage of 3.7 V (cite:). A 2-cell stack would exceed the charger's voltage regulation range.
