  • Patent number: 5896058
    Abstract: A high speed totem pole FET driver circuit with differential cross-conduction prevention. The driver circuit includes first and second switching elements coupled to a first node, and third and fourth switching elements coupled to a second node. The first node is coupled to a first current source, a pulldown circuit, and the input of the third switching element. The second node is coupled to a second current source, a pullup circuit, and the input of the second switching element. Trigger inputs are applied to the inputs of the first and fourth switching elements to switch the first and fourth switches ON and OFF, wherein the two trigger inputs are of opposite phase so that when one input is HIGH (LOW) the other input is LOW (HIGH). The second switching element may include a comparator circuit with its non-inverting input coupled to the second node, its inverting input coupled to a power source via a V.sub.
