BQ25619RTWR Description

Short technical summary and product information.

The Texas Instruments BQ25619RTWR is an I2C controlled, single-cell buck battery charger designed for charging Li-Ion/Li-Polymer and Lithium Phosphate batteries. It supports a maximum charge current of 1.5A and features a low termination current of 20mA. The device operates with an input voltage range from 3.9V to 13.5V, with an absolute maximum rating of 22V.

 

Key features include a high-efficiency synchronous switch-mode buck charger operating at 1.5MHz, achieving up to 95.5% charge efficiency. It offers ±0.5% charge voltage regulation and programmable input current limits from 100mA to 3.2A. The charger also includes a 1A boost mode with an output voltage range of 4.6V to 5.15V.

 

Designed for wearable accessories, the BQ25619RTWR is housed in a 24-WQFN (4x4mm) package. It operates within an ambient temperature range of -40°C to 85°C. The device integrates features like input over-voltage protection (OVP), input current limit (IINDPM), and input voltage limit (VINDPM) for robust power management. It supports USB input, high-voltage adapters, or wireless power sources.
