BQ294705DSGR Description

Short technical summary and product information.

The BQ294705DSGR is an integrated circuit from Texas Instruments designed for overvoltage protection in Lithium-Ion battery pack systems. It independently monitors each cell for overvoltage conditions and features an external capacitor-programmed delay timer. The device provides high-accuracy overvoltage protection with a threshold range of 3.85V to 4.6V and an accuracy of ±10mV.

 

Key features include low power consumption with ICC approximately 1µA and low leakage current per cell input below 100nA. The BQ294705DSGR is available in an 8-pin WSON package with a small footprint, measuring 2.00mm x 2.00mm. It supports 2-, 3-, and 4-series cell configurations and offers output options for active high or open drain active low.

 

This battery protector is suitable for applications requiring reliable overvoltage detection and prevention to ensure battery safety and longevity. The device operates within a temperature range of -40°C to 85°C and is surface-mountable.
