The BQ7790502PWR from Texas Instruments is an ultra-low-power, stackable battery protector IC suitable for 3 to 5 series Lithium Ion and Lithium Phosphate battery applications. It provides a full suite of voltage, current, and temperature protections, including overvoltage, undervoltage, overcurrent discharge, short-circuit discharge, over-temperature charge/discharge, and under-temperature charge/discharge.
Key electrical specifications include a typical operating current of 6 µA in normal mode and a shutdown current of 0.5 µA maximum. The device supports an input voltage up to 25V and has an absolute maximum rating of 36V per cell input. Voltage protection accuracy is ±10 mV, with overvoltage protection ranging from 3V to 4.575V and undervoltage protection from 1.2V to 3V.
Current protection includes overcurrent discharge 1 and 2, and short-circuit discharge. Temperature protection thresholds are set for both charging and discharging conditions. The IC features independent charge (CHG) and discharge (DSG) FET drivers and built-in self-test functions for high reliability.
Packaged in a 20-TSSOP, the BQ7790502PWR is designed for surface mount applications. Its scalable cell count capability allows for use in systems ranging from 3 to 20 series cells or more. The device is also Functional Safety-Capable, with documentation available to aid in functional safety system design.
