I. Battery Fuel Gauges: Precise Power Measurement, Eliminating Range Anxiety

The battery meter acts as the ‘smart meter’ of the battery system. Its core function is to precisely monitor key parameters such as the battery’s **State of Charge (SOC), State of Health (SOH), remaining capacity, and charge/discharge current**, providing real-time, reliable power data to the device. This prevents issues such as misjudgements of battery levels and sudden changes in range, and is compatible with a variety of battery chemistries, including single-cell and multi-cell series-connected lithium-ion and nickel-metal hydride batteries.

Core Technical Advantages

- Enhanced by patented algorithms for maximum measurement accuracy: Equipped with TI’s proprietary algorithms—including Impedance Track™, Dynamic Z-Track™, and CEDV (Compensated End-of-Discharge Voltage)—it overcomes the limitations of traditional voltage monitoring. By comprehensively considering factors such as battery internal resistance, depth of discharge, temperature, and load fluctuations, it achieves ultra-high-precision SOC calculation even under dynamic load conditions and in extreme temperature environments, with an error margin far below industry standards.

- Full-scenario compatibility, covering multiple cell configurations: The product range covers various specifications, including single cells, 2–4 cells in series, and 4 or more cells in series. It caters to diverse applications such as consumer electronics (mobile phones, laptops, TWS), industrial equipment and electric vehicles. Certain models support battery monitoring for up to 15 cells in series, meeting the requirements of high-voltage battery packs.

- Integrated design balancing functionality and cost: Several battery management ICs incorporate additional features such as basic protection, authentication and cell balancing, enabling multi-task control via a single chip. This simplifies circuit design and reduces BOM costs, whilst supporting multiple communication interfaces including SMBus, I2C and HDQ for seamless integration with host control systems.

Typical Products and Applications

The BQ40Z50-R2, BQ41Z50 and BQ27Z746 are flagship products in TI’s battery monitor range. Widely used in laptops, portable medical devices, electric bicycles and robotic vacuum cleaners, they meet both the low-power requirements of compact consumer electronics and the high-stability demands of industrial equipment, enabling precise battery level display and efficient runtime management.

II. Battery Monitors and Balancers: Real-time Monitoring of Cell Status, Balancing to Extend Battery Life

In multi-cell series battery packs, inconsistencies between cells can lead to uneven charging and discharge limitations, significantly shortening battery life. TI’s battery monitors and balancers focus on **precise cell-level monitoring and active/passive balancing control**, collecting real-time data on the voltage, temperature and series current of each cell. They synchronously regulate cell charge levels to eliminate voltage differences, improve the overall capacity utilisation of the battery pack and extend the battery’s cycle life.

Key Features

- High-precision cell monitoring with zero data deviation: Featuring ultra-high voltage monitoring accuracy of ±5mV at 25°C, it supports time-synchronised measurements to capture real-time changes in the status of each cell. Additionally, built-in noise filtering circuits ensure stable and reliable monitoring data even in complex electromagnetic environments such as automotive electronics and industrial equipment, providing an accurate basis for balancing control.

- Intelligent balancing control, suitable for diverse scenarios: Supports both autonomous balancing and host-controlled balancing modes, compatible with passive balancing and partial active balancing solutions. It can automatically initiate balancing operations based on battery status, effectively resolving cell voltage differential issues. The product covers 3–16-cell configurations and can be stacked to support battery packs with high cell counts, making it suitable for high-power applications such as new energy vehicles, energy storage systems and industrial battery packs.

- Multi-layered protection coordination: ensures both safety and monitoring: Integrated fault monitoring and early warning functions for overvoltage, undervoltage, overcurrent and overtemperature, coupled with flexible communication interfaces (I2C, SPI, high-speed data queues), enable rapid upload of fault information and triggering of protective actions, achieving an integrated solution for monitoring, balancing and basic protection.

Typical Products and Applications

Products such as the BQ76952, BQ76942 and BQ79716B-Q1 have demonstrated outstanding performance. The automotive-grade models meet ASIL-D and ASIL-B functional safety requirements and are suitable for power battery packs in hybrid and pure electric vehicles; the industrial-grade models are widely used in energy storage stations, electric forklifts and high-voltage power tools, helping multi-cell battery packs achieve maximum lifespan and operational stability.

III. Battery Protectors: Fortifying Safety Defences and Eliminating Battery Hazards

Battery protectors act as the ‘safety gatekeepers’ of battery systems. They provide rapid, reliable hardware-level protection against critical risks such as overcharging, over-discharging, overcurrent, short circuits and overheating in lithium-ion batteries. By interrupting hazardous circuits, they prevent safety incidents such as battery fires, explosions and electrolyte leakage, safeguarding both equipment and users. As such, they are indispensable core components for all battery-powered devices.

Core Protection Features

- Ultra-fast response, robust hardware-level protection: Utilises a hardware-driven protection mechanism with a fault response time measured in microseconds, far faster than software-based solutions. Upon detecting anomalies such as overvoltage, undervoltage, short circuits or overcurrent, it immediately triggers MOSFETs to shut down the charge/discharge circuit, preventing the spread of danger; supports high-side and low-side N-FET driving to accommodate different battery pack circuit designs.

- Comprehensive protection covering all operating conditions: Integrates multiple functions including cell voltage protection, battery pack current protection, temperature protection and internal diagnostic protection. Customised protection thresholds are set for all operational risk points, including charging, discharging, idle and short-circuit conditions. Some models support multi-level protection (Level 1 warning, Level 2 hard protection), balancing safety with equipment availability.

- Low power consumption and high stability, suitable for harsh environments: Features ultra-low standby power consumption and a sleep mode to reduce battery self-discharge; designed for a wide operating temperature range, withstanding extreme environments from -40°C to 150°C, whilst supporting multiple lithium battery systems (lithium-ion, lithium-polymer, lithium iron phosphate, lithium titanate), suitable for various specialised and standard applications.

Typical Products and Applications

The BQ76907 and BQ76940 are classic models in TI’s battery protection portfolio, combining both monitoring and protection functions. Their compact packaging facilitates space-saving layouts, and they are widely used in portable consumer electronics, power tools, smart home devices, and light electric vehicles. These devices provide the final line of defence for battery systems, meeting stringent global safety certification standards.
