TPS62135RGXR_CSD16570Q5B MOS (Field Effect Transistor) Guide

The BQ25790 and BQ25792 enable efficient charging of USB Type-C™ and USB Power Delivery (PD) ports in small personal electronics, portable medical devices, and building automation applications, and can reduce quiescent standby current by a factor of 10. Texas Instruments (TI) today introduced the industry's smallest buck-boost battery charger integrated circuit that integrates power path management for greater power density, universal and fast charging with up to 97 percent efficiency. .

. The newly introduced C2000 F2838x microcontrollers, however, do not rely on external ASICs, thereby reducing the overall solution size and the amount of material used. Systems with a communication interface often require an external application-specific integrated circuit (ASIC) or a dedicated host-controlled microprocessor, but this reduces the flexibility of the design architecture, increases complexity, and takes up space on the circuit board.

A large number of 150mm fabs in the industry were closed, and more and more 300mm fabs were launched and gradually achieved mass production. So, does this mean that 150mm wafers are gradually withdrawing from the stage of history? The answer is no, there is still a huge market space for 150mm wafers.

Ray Upton, TI's vice president of connected microcontrollers, explained that new technologies are critical to "moving large amounts of data in a stable manner," improving high-performance communications. .

Thanks to these features and its selectable functions, the TPS62840 helps engineers overcome key design challenges in many battery-operated, continuous-run industrial and personal electronics applications, including narrowband IoT, grid infrastructure equipment, and renewable energy. Wearables, they all require greater flexibility and precision, wider wireless range, and reduced electromagnetic interference (EMI).

Flexible VIN broadens application range: The TPS62840 has a wide input voltage range of 1.8VIN-6.5VIN and accepts a variety of chemistries and configurations, such as two lithium-manganese dioxide (2s-LiMnO2) cells in series , single-cell lithium thionyl chloride (1xLiSOCL2) batteries, four- and two-cell alkaline batteries, and lithium polymer batteries (Li-Po).

In short, advances in BAW technology have brought "higher performance, simpler design, lower cost and smaller size" to wired and wireless networks, Wong explained.

One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer. 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. 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.

"The new BAW resonator technology is important because TI is integrating it into its silicon products, reducing design time, solution size and component cost," said Philip Solis, research director for connectivity and smartphone semiconductors at IDC.

TI's new product announcement includes an industry-first crystalless wireless microprocessor (MCU) that integrates a TI BAW resonator in a package. Design engineers can use this MCU to achieve simpler and smaller designs while improving performance and reducing cost. . Time-to-market is accelerated as designers eliminate the need to screen, calibrate and assemble external quartz crystals.

The particles in the solid vibrate in an elliptical trajectory, and the long axis of the ellipse is perpendicular to the surface of the solid. . For SAW, also called Rayleighsurface wave, there are both longitudinal waves and transverse waves.
