AD1028ARQ_AD1896AYRS Introduction

The BQ25790 and BQ25792 enable efficient charging of USB Type-C™ and USB Power Delivery (PD) ports in small personal electronics, portable 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 BQ25792 is available in a 4mm x 4mm, 29-pin QFN package and is available now from TI and authorized resellers. 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. Complete reels and custom reels are available on TI.com and through other channels, starting in 1,000 pieces.

The working principle is as shown below. The typical basic structure is shown in the figure (a) above, with the piezoelectric layer sandwiched between the upper and lower metal electrodes, the corresponding mBVD equivalent circuit is shown in the figure (b) above, and the corresponding impedance is shown in the figure (c) above. It can be seen that there are two resonance frequencies, series (fs) and parallel (fp).

Physically, waves are mainly divided into two types, one is electromagnetic wave, which does not require any medium, but propagates through the periodic oscillation of the electric and magnetic fields generated by the initially charged particles, so in a vacuum can also spread. Radio waves, microwaves, visible light, X-rays, and gamma rays are all electromagnetic waves.
