The TPSI8830 is an isolated solid-state relay designed for industrial applications. The TPSI8830 uses TI’s high reliability capacitive isolation technology in combination with internal back-to-back MOSFETs to form a completely integrated option requiring no secondary side power supply. The TPSI8830 improves system reliability as TI’s capacitive isolation technology does not suffer from mechanical wear-out or photo degradation failure modes common in mechanical relay and photo relay components.

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 must connect to a system supply from 3.0V to 5.5V and the EN pin of the device must be driven by a GPIO output with logic HI from 1.8V to 5.5V. In other applications, the VDD and EN pins can be driven together directly from the system supply or from a GPIO output.

The secondary side consists of back-to-back MOSFETs with a standoff voltage of ±80V from S1 to S2. The TPSI8830 integrates bidirectional overcurrent protection to prevent damage due to output miswiring or short to ground.
