BQ24640RVAR Description

Short technical summary and product information.

The BQ24640RVAR from Texas Instruments is an advanced battery charge controller IC specifically designed for supercapacitor applications. This device operates as a standalone, synchronous, switched-mode buck controller, offering high efficiency for charging supercapacitor packs from 2.1V to 26V.

 

Key electrical specifications include an input voltage range of 5V to 28V (absolute maximum 33V) and a maximum charge current of 10A. The controller provides precise charge voltage and current regulation with accuracies of ±0.5% and ±3%, respectively. It supports 1 to 8 series cells and is suitable for supercapacitor chemistries.

 

The BQ24640RVAR features integrated loop compensation and digital soft-start, simplifying design. Safety features include input overvoltage protection, capacitor temperature sensing with hot and cold charge suspend capabilities, and thermal shutdown. The device operates within a temperature range of -40°C to 85°C.

 

Packaged in a 16-VQFN (3.5x3.5mm) with exposed pad, this surface-mount component is ideal for applications such as memory backup systems, industrial UPS systems, and power transient buffering.
