Power trends

Power management is at the center of enabling the continued integration of electronics in our lives. For decades, TI has been at the forefront of developing new process, packaging and circuit-design technologies to deliver the best power devices for your design. Check out our featured battery monitor and balancers below, designed to help you address low noise and precision challenges.

Battery monitors & balancers for low noise & precision

Enable time-synchronized measurements across each individual battery-cell with high-accuracy battery-cell voltage monitoring and fault detection.

For an effective and cost optimized solution for battery management systems in HEV/EV, our automotive battery monitors and balancers integrate noise filtering to minimize and ultimately eliminating the need for external components. Eliminating the need for external noise filtering  can improve measurement integrity and accuracy, channel-to-channel measurement synchronization and reduce the time for all measurements to return to the host.

For industrial systems, such as e-bikes, e-scooters, power and garden tools, our monitors with integrated, programmable protection give full control over voltage, current and temperature, automatically triggering fuse and on-board diagnostics for optimal system performance. This combined with industry-leading accuracy helps you maximize the run time of your battery while maintaining integrity of the overall system.
