Texas Instruments introduces new isolation product family that extends service life in high-voltage applications to more than 40 years

• Pin-to-pin replacement for optocouplers, improving signal integrity and reducing power consumption by up to 80%

• New optocoupler simulator leverages TI's proprietary SiO2-based isolation technology to improve end product performance throughout its lifecycle

Shanghai, China (September 20, 2023) - Texas Instruments (TI) today launched a new family of optocoupler simulators 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 the first optocoupler simulator from Texas Instruments that is pin-to-pin compatible with common optocouplers in the industry, allowing seamless integration into existing designs while fully leveraging the unique advantages of silicon dioxide (SiO2)-based isolation technology .

“As electrification continues and high-voltage power systems become more complex, engineers need to ensure the correct isolation levels while improving the performance and life of their products,” said Tsedeniya Abraham, general manager of interface products at TI. “Our new family of optocoupler simulators meets the growing demand for reliable, cost-effective isolation technology and demonstrates our commitment to investing in high-voltage technologies.”

Improve reliability with Texas Instruments' SiO2-based isolation technology

Optocouplers have been a popular choice for engineers in the past by integrating an LED to isolate the signal, but optocouplers require pre-overdesign to compensate for the inevitable aging effects of LEDs. Texas Instruments' optocoupler simulators use SiO2 isolation barriers, eliminating the need for overdesign and completely eliminating the aging effects of LEDs. Texas Instruments' SiO2 isolation barriers have a high dielectric strength of 500VRMS/μm, allowing the new device product family to provide more than 40 years of protection for end product designs. The optocoupler simulators also provide up to 3,750VRMS of isolation protection while reducing power consumption by up to 80%.

Additionally, the product family operates over a wide –55°C to 125°C temperature range while providing up to 10 times better common-mode transient immunity than optocouplers.

Texas Instruments' new family of optocoupler simulators continues the company's commitment to helping engineers unlock the potential of high-voltage applications.
