The BQ7791502PWR from Texas Instruments is an ultra-low-power primary protector IC for 3 to 5 series Lithium Ion/Polymer battery stacks. It provides a full suite of voltage, current, and temperature protections, including overvoltage, undervoltage, overcurrent during charge and discharge, short-circuit discharge, and overtemperature protection.
This device features autonomous cell balancing and supports stackable configurations for scalability to 20 series cells or more. It operates with a typical quiescent current of 8 µA in normal mode and 2 µA in HIBERNATE mode, making it suitable for low-power applications. The IC is housed in a 24-TSSOP package and is designed for surface mount.
Key electrical specifications include a maximum input voltage of 25V, overvoltage protection ranging from 3V to 4.575V, and undervoltage protection from 1.2V to 3V. Current protection thresholds are resistor programmable. The operating temperature range is -40°C to 85°C.
