BQ7790505PWR Description

Short technical summary and product information.

The BQ7790505PWR 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, over-temperature, and under-temperature detection.

 

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 consumption of 6 µA in normal mode and a maximum of 0.5 µA in shutdown mode. The BQ7790505PWR is designed for surface mounting in a 20-TSSOP package.

 

Key electrical specifications include overvoltage protection ranging from 3V to 4.575V and undervoltage protection from 1.2V to 3V. Current protection thresholds are defined for overcurrent discharge 1 and 2, and short-circuit discharge. Temperature protection is available for both charging and discharging conditions, with specific thresholds for over and under-temperature events.
