BQ7790503PWR Description

Short technical summary and product information.

The BQ7790503PWR from Texas Instruments is an ultra-low-power, stackable battery protector IC suitable for 3- to 5-series Lithium-Ion and Lithium-Phosphate battery packs. It provides a full suite of protection functions, including overvoltage, undervoltage, overcurrent during discharge, short-circuit discharge, and over/undertemperature protection.

 

Key electrical specifications include a typical operating current of 6 µA in normal mode and a maximum input voltage of 25 V. The device offers precise voltage protection with an accuracy of ±10 mV, with overvoltage thresholds ranging from 3 V to 4.575 V and undervoltage thresholds from 1.2 V to 3 V. Current protection is also detailed, with specific ranges for overcurrent discharge and short-circuit discharge.

 

Thermal protection is provided with configurable overtemperature and undertemperature thresholds for both charging and discharging. The IC features independent charge (CHG) and discharge (DSG) FET drivers and a 36-V absolute maximum rating per cell input. It is designed for high reliability with built-in self-test functions and is Functional Safety-Capable.

 

Packaged in a 20-TSSOP, the BQ7790503PWR is designed for surface mounting. Its scalable cell count capability allows for configurations from 3 to 20 series cells or more, making it versatile for various battery management applications.
