Professional magazine and portal dedicated to electronics TI drives isolation technology forward with new solid-state relays that provide industry-leading reliability
Building on more than two decades of experience developing new isolation manufacturing technologies and integrated circuits (ICs) for high-voltage systems, Texas Instruments introduced a new portfolio of solid-state relays, including automotive-qualified isolated drivers and switches, that deliver industry-leading reliability to help make electric vehicles (EVs) safer. The new isolated solid-state relays also provide the smallest solution size while reducing the bill-of-materials (BOM) cost of powertrain and 800-V battery-management systems.
The TPSI3050-Q1 isolated switch driver with an integrated 10-V gate supply and the TPSI2140-Q1 1,400-V, 50-mA isolated switch both integrate power and signal isolation across a single barrier using a unique approach that improves reliability, while significantly reducing solution size and cost compared to existing electromechanical relays and solid-state photorelays. The devices are the first in a new solid-state relays portfolio that will also include ICs designed for high-voltage industrial applications (more info).
