Abstract
A dead-time generator for incorporation in an integrated circuit wherein the integrated circuit includes a high side and low side gate driver and wherein the high side and low side gate driver drive output switches such that a dead-time is provided between on times of the output switches, the dead-time generator comprising a circuit internal to the integrated circuit having an external terminal at which a dead-time setting component is connected, and wherein the dead-time generator comprises a circuit for providing a discrete dead-time for a range of dead-time setting values at the dead-time setting terminal and wherein, for a plurality of ranges of dead-time setting values at the dead-time setting terminal, the dead-time generator generates an associated plurality of discrete dead-times.
