BQ24133RGYR Description

Short technical summary and product information.

The BQ24133RGYR from Texas Instruments is a highly integrated, standalone synchronous switched-mode battery charger. It is designed to charge 1, 2, or 3 cell Lithium Ion and Li-Polymer batteries with a maximum charge current of 2.5A. The device operates from an input voltage range of 4.5V to 17V, with an absolute maximum rating of 20V, and features adjustable overvoltage protection.

 

Key electrical specifications include a charge voltage regulation accuracy of ±0.5%, charge current regulation accuracy of ±5%, and input current regulation accuracy of ±6%. The charger operates at a switching frequency of 1.6 MHz, achieving up to 92% efficiency. It includes features such as battery thermistor monitoring, IC thermal regulation, input current limiting (IINDPM), and input overvoltage protection (OVP).

 

This charger is housed in a 24-VQFN package with surface mount mounting type. The operating temperature range is -40°C to 85°C. It offers automatic power path selection between adapter and battery, dynamic power management, and integrated 20V switching MOSFETs. Safety features include thermal regulation, thermal shutdown, battery thermistor sense for charge suspend, and cycle-by-cycle current limiting.
