Additionally, its maximum operating current is 10mA.

The use of the BQ296114DSGR helps ensure safety and reliability in the design of power systems by efficiently monitoring and protecting Li-ion battery cells, when compared to conventional designs that require the design and integration of discrete components, relays, and opto-couplers.

Application Fields

The BQ296114DSGR is used in a wide variety of applications, including energy storage systems (ESS), lithium-ion power banks, mobile power systems, laptop computers, battery powered medical equipment, and portable consumer electronics. Additionally, this IC is unique in that it provides a high level of reliability and safety for the products it powers, specifically in terms of protecting the Li-ion cells from over-charge, over-discharge, over-current, over-temperature, and short-circuit conditions.

The BQ296114DSGR can also be used in electric vehicle and energy storage system applications, such as battery packs, battery packs, and electric vehicle battery management systems. This device supports advanced features and functions that are essential for the efficient and reliable operation of a Li-ion battery pack, such as over-charge protection, over-discharge protection, over-current protection, temperature monitoring, and safety circuit implementation.

Working Principle

The BQ296114DSGR operates in three main modes: monitoring, protection and control. The monitoring mode is used to detect the battery voltage, current and temperature, provide data to the control system, and ensure the safety of the battery. The protection mode prevents the battery from being overcharged, over-discharged or exposed to high temperatures, by activating a special circuit to prevent over-heating or over-depletion of the energy storage system.

The control mode is used to manage and control the energy storage system, allowing the user to monitor and control the energy storage system remotely, such as turning on and off the charging system, or setting charging parameters. The synchronous rectification circuit also reduces the switching losses in the operating system, resulting in an improved efficiency.

Conclusion

In conclusion, the BQ296114DSGR is a highly advanced battery management IC designed to ensure safety and reliability in the design of Li-ion battery pack. By using this single-cell battery management device, designers are able to integrate a much needed set of features and functions required for the efficient and reliable operation of energy storage systems and other battery powered equipment.
