BQ7791506PWR Description

Short technical summary and product information.

The Texas Instruments BQ7791506PWR is a highly integrated battery protection IC designed for multi-cell Lithium Ion/Polymer battery packs. It provides a full suite of voltage, current, and temperature protections without requiring a microcontroller. The device supports 3 to 5 series cells and features an ultra-low quiescent current of 8 µA in normal mode, making it ideal for power-sensitive applications.

 

Key protection features include overvoltage, undervoltage, overcurrent discharge (two levels), and short-circuit discharge. It also offers overtemperature and undertemperature protection for both charging and discharging conditions. The BQ7791506PWR includes independent charge and discharge FET drivers and a smart passive cell balancing algorithm with integrated FETs, capable of up to 50 mA balancing current. It is supplied in a 24-TSSOP surface mount package.

 

This device is suitable for applications such as power tools, e-bikes, and robotic cleaners, where reliable battery protection and scalability are essential. Its stackable interface allows for scaling to support battery packs from 3 to 20 series cells or more. The device is also functional safety-capable, with documentation available to aid system design.
