Texas Instruments launches new isolation product line to extend service life of high-voltage applications to more than 40 years


 

【Lansheng Technology News】Texas Instruments today launched a new optocoupler emulator product series based on signal isolation semiconductor technology, designed to improve signal integrity, reduce power consumption and extend the service life of high-voltage industrial and automotive applications. This is Texas Instruments’ first optocoupler emulator that is pin-to-pin compatible with common optocouplers in the industry, allowing seamless integration into existing designs while taking full advantage of silicon dioxide (SiO2)-based isolation technology. unique advantages.


"As electrification continues and high-voltage power systems become more complex, engineers need to increase the performance and longevity of their products while ensuring the correct isolation levels," said Tsedeniya Abraham, general manager of interface products at Texas Instruments. "Our new The optocoupler emulator product line not only addresses the growing demand for high-reliability, cost-effective isolation technology, but also demonstrates our commitment to invest in high-voltage technology."


Improve reliability with Texas Instruments SiO2-based isolation technology

Optocouplers, which isolate signals by integrating an LED, have been a common choice for engineers in the past, but optocouplers require over-margin design in advance to compensate for the inevitable aging effects of LEDs. Texas Instruments' optocoupler simulator uses a SiO2 isolation barrier, eliminating the need for over-margin design and completely eliminating the aging effects of LEDs. Texas Instruments' SiO2 isolation barriers feature a high dielectric strength of 500VRMS/μm, enabling the new device family to protect end product designs for more than 40 years. Optocoupler emulators also provide isolation protection up to 3,750VRMS while reducing power consumption by up to 80%.


In addition, the product family tolerates a wide operating temperature range of –55°C to 125°C while providing up to 10 times greater common-mode transient immunity than optocouplers.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
