The TPSI2240-Q1 is an isolated solid state relay designed for high voltage automotive and industrial applications. The TPSI2240-Q1 uses TI’s high reliability capacitive reinforced isolation technology in combination with internal back-to-back MOSFETs to form an integrated solution requiring no secondary side power supply.

The primary side of the device is powered by only 5mA of input current and incorporates a fail-safe EN pin preventing any possibility of back powering the VDD supply. In most applications, the VDD pin of the device should be connected to a system supply between 4.5V – 20V and the EN pin of the device should be driven by a GPIO output with logic HI between 2.1V – 20V. In other applications, the VDD and EN pins could be driven together directly from the system supply or from a GPIO output. All control configurations of the TPSI2240-Q1 do not require additional external components such as a resistor and/or low side switch that are typically required in photo relay solutions.

The secondary side consists of back-to-back MOSFETs with a standoff voltage of ±1.2kV from S1 to S2. The TPSI2240-Q1 MOSFET’s avalanche robustness and thermally conscious package design, allow it to robustly support system level dielectric withstand testing (HiPot) and DC fast charger surge currents of up to 1mA (0.6mA for TPSI2240C-Q1 and 3mA for TPSI2240T-Q1) without requiring any external components.
