BQ24151AYFFR Description

Short technical summary and product information.

The BQ24151AYFFR from Texas Instruments is a highly integrated, switch-mode battery charger designed for single-cell Li-ion and Li-polymer batteries. It offers a maximum charge current of 1.25A and supports an input voltage up to 6V, with an absolute maximum rating of 20V.

 

This device features high-accuracy voltage and current regulation, with charge voltage accuracy of ±0.5% at 25°C and ±1% from 0°C to 125°C. Input current regulation accuracy is ±5% for 100mA and 500mA settings. The charger operates with a synchronous fixed-frequency PWM controller at 3 MHz, supporting up to 99.5% duty cycle.

 

Programmable features include input current, fast-charge/termination current, and charge voltage (3.5V to 4.44V) via an I2C interface. It includes robust protection features such as over-temperature and over-voltage protection. The BQ24151AYFFR is available in a compact 20-DSBGA package, suitable for surface mounting.

 

Note: This product is not recommended for new designs. Consider alternate products for new projects.
