2.3.2 TPSI2240-Q1

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 approach requiring no secondary side power supply.
