The low IQ of the TPS62840 enables 80% efficiency at 1-µA loads, 30% higher than comparable devices in the industry. . Longer battery life and very high light load efficiency: Lower IQ consumption provides longer IQ for very light loads (below 100µA) and systems operating primarily in standby/factory mode (no switching) battery life.

The HDC1080 is a digital humidity sensor with integrated temperature sensor from Texas Instruments that provides excellent measurement accuracy with ultra-low power consumption. The HDC1080 supports a wide operating supply voltage range and offers low cost and low power consumption for a variety of common applications compared to competing solutions. . Humidity and temperature sensors are factory calibrated.

The F2838x microcontrollers integrate three industrial communication protocols, enabling designers to tailor a microcontroller to the specific needs of each system. A key component required to achieve this is a new connection manager based on the Arm® Cortex®-M4 subsystem, which reduces some of the processing-intensive communications and optimizes connectivity.

In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. Today, timing often requires a quartz crystal. "Everyone uses quartz crystals for clocks," Solis said.

. The BQ25792 is available in a 4mm x 4mm, 29-pin QFN package and is available now from TI and authorized resellers. Complete reels and custom reels are available on TI.com and through other channels, starting in 1,000 pieces. The BQ25790 is available in a 2.9mm x 3.3mm, 56-pin WCSP package and is available now from TI and its authorized resellers.

Due to its wide application, analog chips are less affected by a single downstream boom. From the historical data, from 2000 to 2017, the volatility of analog chips was 1.8%, while the volatility of typical cyclical industry memory over the same period was as high as 6.7%.

The technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

The overall effect of this structure is equivalent to contact with air, and most of the sound waves are reflected back. This structure is called BAW-SMR (Solidly Mounted Resonator), as shown below. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer. The reflector consists of several layers of alternating high and low impedance layers. For example, one layer has a large acoustic wave impedance, the second layer has a small acoustic wave impedance, and the third layer has a large acoustic wave impedance, and the thickness of each layer is λ/4 of the acoustic wave, so that most waves will The reflected back and the original wave are superimposed.

There are also different structures where sound waves propagate as transverse waves. In the above-mentioned BAW-SMR and FBAR?filter diagrams, sound waves propagate in the form of longitudinal waves, that is, the direction of particle vibration and the direction of wave propagation are parallel.

Only the ladder type and lattice type are briefly introduced here. The BAW filter can connect multiple resonators according to a certain topology. There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter.
