BQ24185YFFR Description

Short technical summary and product information.

The BQ24185YFFR from Texas Instruments is a highly efficient, fully integrated switch-mode battery charger IC. It is designed for single-cell Lithium-Ion and Li-Polymer battery packs, offering full USB compliance and USB On-The-Go (OTG) support.

 

Key electrical specifications include a maximum charge current of 1.5A, an input voltage range from 4V to 16V (with an absolute maximum of 20V), and a battery charge voltage range of 3.5V to 4.44V. The device utilizes a switch-mode buck control topology and operates with a synchronous fixed-frequency PWM controller at 3 MHz. It offers high-accuracy voltage and current regulation, with charge current regulation accuracy of ±5% and charge voltage regulation accuracy of ±0.5% at 25°C.

 

Programmable features are accessible via an I2C compatible interface, allowing for timer functions and other parameter adjustments. The IC includes comprehensive fault protection, such as over-temperature and over-voltage protection, as well as reverse leakage protection to prevent battery drainage. Its operating temperature range is -40°C to 85°C.

 

The BQ24185YFFR is supplied in a compact 25-pin DSBGA (YFF) package, suitable for surface mounting. This makes it an ideal solution for space-constrained applications like mobile phones, smartphones, portable media players, and handheld devices.
