This reference design shows how to achieve overcurrent and overtemperature protection for a solid-state relay. The reference design features the TPSI3050-Q1 5 kVRMS reinforced isolated switch driver. TPSI3050-Q1 device integrates a laminate transformer to achieve isolation while transferring signal and power to the secondary side. This removes the need for any isolated bias supply. In addition, the TPSI3050-Q1 device can supply power to external circuitry located on the high voltage (HV) side. This reference design can support up to 500 VDC or 350 VAC switching with a max of 4 A loading conditions.
