TI Launches New Solid State Relays that Can Provide Outstanding Reliability in the Industry

     Texas Instruments recently launched a new series of solid-state relay products, including automotive standard isolation drivers and switches, which can provide excellent reliability in the industry and help improve the safety of electric vehicles (EVs). These new isolated solid state relays also support ultra small size solutions while reducing the bill of materials (BOM) costs for powertrain and 800V battery management systems.

     The TPSI3050-Q1 isolated switch driver with integrated 10V grid power supply and the TPSI2140-Q1 1400V, 50mA isolated switch use a unique method to integrate power and signal isolation through a single barrier, thus improving reliability, while significantly reducing the size of the solution and reducing costs (compared with existing electromechanical relays and solid-state optical relays). These devices are the first of a new series of solid-state relays, which will also include integrated circuit devices designed for high-voltage industrial applications.

     "High voltage systems are becoming more and more popular, especially with the popularity of electric vehicles. At TI, we are very focused on finding new solutions to complex isolation problems for system designers, such as ensuring reliable and safe operation of vehicles when the industry is transitioning to 800V batteries, while reducing the size of the solution and reducing costs," said Troy Coleman, vice president and general manager of power switches, interfaces and lighting at Texas Instruments (TI). "By integrating more functions into isolation technology, our new solid-state relays enable engineers to reduce the size, cost and complexity of high-voltage power supplies while ensuring the safety of next-generation automotive and industrial systems."
