The BQ7790500PWR 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 during discharge, short-circuit discharge, and over/undertemperature protection.
This device features independent charge (CHG) and discharge (DSG) FET drivers and a 36-V absolute maximum rating per cell input. It operates with a typical current of 6 µA in normal mode and a shutdown current of 0.5 µA maximum. The voltage protection accuracy is ±10 mV, with overvoltage protection ranging from 3 V to 4.575 V and undervoltage protection from 1.2 V to 3 V. Current protection includes overcurrent discharge and short-circuit discharge limits.
Packaged in a 20-TSSOP, the BQ7790500PWR is designed for surface mount applications. Its operating temperature range is -40°C to 85°C. The IC is also Functional Safety-Capable, with documentation available to aid in functional safety system design. Additional features include open cell and open-wire detection, and built-in self-test functions for high reliability.
