Introduction to BQ296106DSGR

The BQ296106DSGR is a high-performance multi-channel synchronous Buck (converting from a higher to a lower voltage) battery management system from Texas Instruments specifically designed for lithium ion batteries. It offers a wide input voltage rage (4.5V to 42V) and the ability to achieve wide output range. It consists of a fast-switching synchronous Buck controllers for each cell with an integrated fast 10A PFET and a 12A low side PFET, 16 ADC channels for monitoring Voltages, and a flexible serial peripheral Interface (SPI) interface compliant with Battery Management System (BMS) protocols.

Application Fields

The BQ296106DSGR has a wide range of applications, including entry level consumer electronics, low power power supplies, and automotive applications. It is suitable for applications like mid-size 4- and 6-cell battery packs, 10 cell battery packs, dual cell LED flasher applications and 12V HEV, Electric Vehicle (EV) and Electric Bicycle (EB) applications. It can be used to manages a wide range of battery types, including both cylindrical and prismatic cells, different chemistries, including Li-ion, LiFePO4 and NiMH.

In automotive applications, it is used for short range electric vehicles. Because it has a wide operating temperature range, and because it is designed for low quiescent current and high efficiency operation, it is very well suited for peak power applications. It can also be used for hybrid power systems, where it can be used to both boost and buck in order to achieve the most efficient power delivery.

Working Principle

The BQ296106DSGR uses a fast synchronous Buck controller which allows it to switch quickly in order to manage peaks in power demand and provide a wide range of output voltages. It is able to accurately monitor voltages, current and temperatures to ensure that the battery pack is safely balanced and managed throughout its life. The integrated 12A low side PFET and 10A high side PFET are designed for very low power loss operation, enabling efficient and reliable charging and discharging. The total harmonic distortion is minimized, guaranteeing both reliability and operational safety.

The BQ296106DSGR features a wide range of advanced features, such as over-voltage protection, an independent per-cell voltage monitoring and balancing, a built-in slow-charge timer and an integrated voltage supervisor, which allows it to continuously monitor and maintain the desired output voltage levels. The device can also be used to communicate with the main components of the vehicle, such as the battery controller, the charger and the batteries themselves, allowing the complete current and voltage operations to be monitored.

The BQ296106DSGR provides protection and communication capabilities, offering power protection and complete monitoring of the system, ensuring the lithium ion battery pack in the vehicle is safely and efficiently managed throughout its lifetime. Since it is designed for low power dissipation, high efficiency, and wide input and output ranges, it is ideal for short range EVs, hybrid power systems, and other automotive applications.
