BQ25890RTWR Description

Short technical summary and product information.

The BQ25890RTWR from Texas Instruments is an advanced single-cell, 5A buck battery charger IC designed for high input voltage applications. It utilizes MaxCharge™ technology for fast charging and supports USB C/PD compatibility, along with integrated USB D+/D-/BC1.2 detection and USB On-the-Go (OTG) boost mode.

 

This charger IC operates with an input voltage range of 3.9V to 14V, with an absolute maximum rating of 22V. It offers a maximum charge current of 5A and a battery charge voltage range of 3.84V to 4.6V. Key electrical features include high charge efficiency up to 93% at 2A and 91% at 3A, and a selectable 500-kHz and 1.5-MHz boost converter with up to 2.4A output.

 

Designed for robust performance, the BQ25890RTWR includes features like Input Current Optimization (ICO), Input Current Limit (IINDPM), Input OVP, IC thermal regulation, and BAT temperature monitoring. It also incorporates an integrated ADC for system monitoring and Narrow VDC (NVDC) power path management for instant-on operation even with no battery or a deeply discharged battery.

 

The device is housed in a 24-WQFN (4x4 mm) package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. The I²C interface allows for flexible control and configuration.
