TPSI2140-Q1 1200-V, 50-mA, Automotive Isolated Switch with 2-mA Avalanche Rating

The TPSI2140-Q1 is an isolated solid state relay designed for high voltage automotive and industrial applications. The TPSI2140-Q1 uses TI’s high reliability capacitive isolation technology in combination with internal back-to-back MOSFETs to form a completely integrated solution requiring no secondary side power supply. The entire primary side of the device requires only 9 mA of input current, enabling the user to drive both the VDD and EN pins from a single microcontroller GPIO and eliminating the need for an external low side switch used in photo relay solutions.
