BQ24250RGER Description

Short technical summary and product information.

The BQ24250RGER from Texas Instruments is a highly efficient, 1-cell, 2A I2C controlled buck battery charger designed for Li-Ion and Li-Polymer batteries. It operates with a maximum input voltage of 10.5V and a minimum input voltage of 4.35V, with an absolute maximum input voltage rating of 22V. The charger supports a battery charge voltage range of 3.5V to 4.44V and offers a programmable charge current up to 2A.

 

Key features include I2C control interface, switch-mode buck topology, and integrated power FETs. The device also incorporates battery temperature thermistor monitoring (JEITA and hot/cold profiles), IC thermal regulation, and an integrated LDO. It provides complete system-level protection including input UVLO, input overvoltage protection (OVP), battery OVP, sleep mode, and input current limit.

 

Packaged in a 24-VQFN (4x4 mm) with a surface mount type, the BQ24250RGER is suitable for various power management applications requiring reliable battery charging.
