Product Description

The BQ24259RGET charger IC by Texas Instruments (TI) is a compact switch-mode Lithium Ion battery management solution designed for single-cell Li-Ion/Li-Polymer batteries. It supports input voltages from 3.9V to 6.2V, delivering up to 2A charge current with an integrated synchronous rectifier for high efficiency. The IC features an I2C interface for programmable charging parameters, USB On-The-Go (OTG) support, and seamless switching between USB and adapter power sources. Operating within -40°C to +85°C, it is ideal for portable devices like smartphones, tablets, and medical equipment, typically paired with 5-inch displays. Key advantages include robust protections (over-voltage, over-current, thermal shutdown) and a 4mm x 4mm QFN package for space-constrained designs. Limitations include reliance on external components for specific functions. Suitable for batteries up to 5000mAh, it ensures reliable charging in diverse conditions. For detailed specs, consult the TI BQ24259RGET datasheet.
