TPSI2140-Q1 Automotive Isolated Switch Texas Instruments TPSI2140-Q1 Automotive Isolated Switch is an isolated solid-state relay (SSR) 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 7.5mA 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. The user can also choose to connect the VDD pin to a system supply between 5V to 20V and drive the EN pin from a GPIO. The EN pin is fail-safe, preventing any possibility of back powering the VDD supply.
