BQ294708DSGR Description

Short technical summary and product information.

The BQ294708DSGR from Texas Instruments is an overvoltage monitor and protector IC specifically designed for Li-Ion battery pack systems. It provides accurate cell-by-cell voltage monitoring, ensuring the battery operates within safe limits.

 

This device features factory-programmed overvoltage protection (OVP) thresholds ranging from 3.85V to 4.6V, with high accuracy of ±10mV. An external capacitor-programmed delay timer is initiated upon detecting an overvoltage condition, allowing for controlled response. The BQ294708DSGR also includes options for active high or open drain active low output states and a customer test mode for production line efficiency.

 

With low power consumption (ICC ≈ 1µA) and low leakage current per cell input (<100nA), this IC is suitable for battery-powered applications. It is housed in a compact 8-pin WSON package with a small footprint (2.00mm x 2.00mm) and is designed for surface mount applications.

 

The operating temperature range is -40°C to 85°C, making it suitable for a variety of environmental conditions. The BQ294708DSGR is a key component for ensuring the safety and longevity of lithium-ion battery packs.
