The BQ24156AYFFR from Texas Instruments is a switch-mode, single-cell Li-Ion/Li-Polymer battery charger IC designed for high efficiency and accuracy. It supports a maximum charge current of 1.55A and operates with an input voltage range of 4V to 9V, with an absolute maximum rating of 20V.
This charger IC utilizes an I2C interface for programming various parameters, including input current limit, VIN DPM threshold, fast-charge/termination current, and charge regulation voltage (3.5V to 4.44V). It offers high-accuracy voltage and current regulation, with charge voltage regulation accuracy of ±0.5% at 25°C and ±1% from 0°C to 125°C. Input current regulation accuracy is ±5% at 100mA and 500mA, and charge current regulation accuracy is also ±5%.
Key features include Input OVP and VINDPM for input voltage regulation, bad adaptor detection, and safety limit registers for maximum charge voltage and current limiting. The device is housed in a 20-DSBGA package and operates within a temperature range of -30°C to 85°C (TA).
Applications for the BQ24156AYFFR include mobile phones, MP3 players, and other handheld devices requiring efficient battery charging solutions.
