11 Galvanic Isolation

Photorelays and mechanical relays are electrically isolated from the switch path, therefore these two controls can be on separate domains based on their isolation voltage rating. In applications which do not require isolation between the control signals, a multiplexer may be used. In systems where isolation is needed, TI offers solid state relay (SSR) solutions such as the TPSI3050-Q1 isolated switch driver.
