BQ25120AYFPT Description

Short technical summary and product information.

The Texas Instruments BQ25120AYFPT is a linear battery charger IC designed for single-cell Li-Ion, Li-Polymer, and Lithium Phosphate (LiFePO4) batteries. It operates with an input voltage range of 3.4V to 5.5V and can withstand an absolute maximum input of 20V. The device provides a programmable charge current up to 300mA and supports a battery charge voltage range from 3.6V to 4.65V.

 

This charger integrates a power path management system, an LDO, and a buck converter, enabling efficient system power delivery even when the battery is deeply discharged. It includes features such as BAT temperature thermistor monitoring with JEITA profile, IC thermal regulation, input overvoltage protection (OVP), and VINDPM for maximizing adapter power. The I2C control interface allows for flexible configuration and monitoring of charging parameters.

 

The BQ25120AYFPT is housed in a 25-pin DSBGA package and operates over a temperature range of -40°C to 85°C. It is suitable for space-constrained portable applications requiring a compact, feature-rich charging solution.
