Abstract: A first gate drive outputs a first drive voltage to turn a first transistor on upon occurrence of a condition in which a voltage at a supply terminal is higher than a voltage at a ground terminal, the output first drive voltage being higher than the voltage at the ground terminal. A second gate drive outputs a second drive voltage to turn a second transistor on, upon occurrence of a condition in which the voltage at the supply terminal is lower than the voltage at the ground terminal, the output second drive voltage being higher than the voltage at the supply terminal.
