Abstract
A gate driver circuit includes at least one driver configured to generate a first gate control signal for a first power disconnect switch and a second gate control signal for a second power disconnect switch in parallel with the first power disconnect switch, and logic configured to implement a delayed turn on time for the second gate control signal compared to the first gate control signal such that the first power disconnect switch turns on before the second power disconnect switch when powering up a load coupled to the first and the second power disconnect switches. The gate driver circuit logic may also be configured to implement a delayed turn off time such that the first power disconnect switch turns off before the second power disconnect switch when powering down the load. Corresponding power conversion circuits, electronic systems, and methods of power disconnect switch control are also described.
