The BQ24157SYFFR from Texas Instruments is a highly integrated switch-mode battery charger IC designed for single-cell Li-Ion and Li-Polymer battery packs. It supports USB compliance and USB-OTG functionality, offering a charge rate of up to 1.55A.
Key electrical specifications include a maximum operating input voltage of 6.5V and an absolute maximum rating of 20V. The device features 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. Charge current regulation accuracy is ±5%, and input current regulation accuracy is also ±5% for 100mA and 500mA.
Programmable features via an I2C compatible interface (up to 3.4 Mbps) allow for customization of input current limit, VIN DPM threshold, fast-charge/termination current, and charge regulation voltage. The charger operates as a synchronous fixed-frequency PWM controller at 3 MHz.
Packaged in a 20-DSBGA (YFF) with surface mount type, the BQ24157SYFFR operates in a temperature range of -40°C to 125°C. It includes robust protection features such as over-temperature, over-voltage, and reverse leakage protection.
