Low IQ technology enables more efficient power management

Posted Date: 2024-01-18

As market demand for battery-powered applications continues to grow rapidly, low IQ Technology helps extend battery life without affecting system performance.

Key takeaways

• Power consumption can be significantly reduced using advanced power devices and battery monitors.
• Low IQ technology enables smaller digital circuits while reducing power loss.
• Fast wake-up time significantly reduces energy consumption.

With the rapid development of electronic technologies and systems, batteries are now ubiquitous, powering a variety of devices including personal electronic devices and electric vehicles (EVs). The trend toward battery power shows no signs of slowing down, and at the same time, the design challenge remains in achieving higher battery performance for longer periods of time.

Low quiescent current (IQ) Technology plays an important role in meeting this challenge. IQ Is the power consumption of the device when it is on but in an inactive state (often called standby or sleep mode). Many battery-operated devices spend 99% of their life in standby mode, powered up only when necessary. Although IQ A low power load is involved, but minimizing it is critical to battery efficiency. Innovative circuit design in Texas Instruments' proprietary BiCMOS process technology helps achieve very low IQand maximize battery run time without affecting system performance.

"Thanks to low-power technology, almost everything can now be powered by batteries," said Siddharth Sundar, battery monitor business unit manager at Texas Instruments. "So with a wider range of devices than ever before, we have to focus when we think about power consumption. Changes have occurred.”

low IQ How technological breakthroughs are driving the development of battery-powered systems

Batteries are rapidly spreading from small personal electronics, such as wireless headphones and laptops, to larger devices, including industrial power tools, electric vehicles and medical instruments.

This trend in batteries is expected to continue as IoT technology rapidly develops in homes, factories and enterprises, making low-IQ Innovation has become an important factor driving efficient energy utilization.

Design engineers have long developed i‌ for personal electronicsQ solutions, but they face different challenges in the larger industrial and automotive applications where batteries are used today.

Electric vehicles need to maintain low power consumption when idle to conserve power, while also needing to be able to smoothly switch to driving high-power dynamic loads. Electric vehicle drivers want to ensure that their vehicles still have enough power to drive after being parked for long periods of time. In the event of an accident or other emergency, electric vehicle drivers also want to be able to make emergency calls through the vehicle's eCall system, which is powered by a separate small battery.

No compromises on performance or cost

As more applications switch to battery power, advances in semiconductor technology are helping to solve design challenges, delivering IQ solution.

Texas Instruments is at the forefront of this innovation with power and battery management devices that enable low power consumption for battery-powered applications without compromising performance, solution size or cost.

For example, Texas Instruments' BQ76952 is a high-precision industrial battery monitor that enables lower power consumption in sleep mode of 1uA to 10uA, while operating power consumption is 200uA to 300uA. In standby operation, this can save 10 to 20 times power consumption while giving users the flexibility to make trade-offs between performance and power consumption in different usage scenarios.

Breakthroughs in process technology also enable design engineers to reduce current leakage in battery management devices. Most leakage comes from large digital circuits, memories, and high-power field-effect transistors (FETs). However, our company's high-density resistors and capacitors combined with new circuit technologies allow digital circuits to become smaller, thereby reducing current leakage and IQ

Vishnu Ravinuthula, director of battery fuel gauge design at Texas Instruments, said: “Using dedicated low-power process technology and appropriate high-voltage components can have a big impact, not only reducing the chip’s IQ, and also extend battery life over the long term. "

Fast wake-up time extends battery life

To lower IQOne way is to prevent current leakage, and the other way is to ensure that the device can switch quickly and efficiently between standby and higher power loads. Power supply accuracy is a measure of how close the actual output is to the programmed value and is typically limited by its load transient response, which is a measure of how quickly the device returns to the target output voltage after a sudden change in load current or supply voltage. Longer transient response times can cause increased power consumption when the device powers up from sleep mode. Our fast wake-up comparator and zero IQ Fast response mechanisms such as feedback control can shorten the transient response time to the greatest extent without affecting low-power performance.

For example, our buck switching regulators and voltage monitors feature the best response and current sense times in the industry. They enable the device to wake up quickly, thus saving power.

“Fast wake-up times not only meet user expectations for convenience, but also significantly reduce energy consumption and improve battery life,” said Vladislav Merenkov, marketing manager for boost converters and controllers at Texas Instruments.

As the growth momentum of electronic products continues unabated, IQ Technological innovation will enable our industry to maximize efficiency in an increasingly diverse and complex range of battery-powered devices. With low standby and shutdown power modes, our IQ Technology extends battery runtime, shelf life, and reduces costs without compromising performance.
