  • Patent number: 10862483
    Abstract: A gate driver includes a high-side region that operates in a first voltage domain, a low-side region that operations in a second voltage domain lower than the first voltage domain, a termination region interposed between the high-side region and the low-side region and configured to isolate the first voltage domain from the second voltage domain, a high-side gate driver disposed in the high-side region and configured to drive a high-side power transistor, a low-side gate driver disposed in the low-side region and configured to drive a low-side power transistor, and a plurality of termination diodes disposed in the termination region and configured to transmit information bits between the high-side region and the low-side region, where each of the plurality of termination diodes includes an anode coupled to the low-side region and a cathode coupled to the high-side region.
