The Texas Instruments BQ7791501PWR is an ultra-low-power primary protector IC for 3 to 5 series Lithium Ion/Polymer battery packs. It provides a full suite of voltage, current, and temperature protections, including overvoltage, undervoltage, overcurrent during charge and discharge, and short-circuit discharge protection. The device also features over-temperature protection for both charging and discharging.
With an operating temperature range of -40°C to 85°C, the BQ7791501PWR is suitable for a wide variety of applications. It operates with a typical current consumption of 8 µA in normal mode and 2 µA in HIBERNATE mode, contributing to extended battery life. The IC is housed in a 24-TSSOP package, designed for surface mounting.
Key protection features include adjustable overcurrent and short-circuit detection, as well as open cell and open-wire detection. The device also supports autonomous cell balancing and has a high 36-V absolute maximum rating per cell input. Its functional safety-capable design aids in system-level safety implementations.
