Abstract
High-performance low-power isolated bootstrapped gate drive apparatus and methods are disclosed for driving high-side and floating transistors. The gate drivers use edge-triggered capacitive-coupled inputs. The gate drivers may include detection and delay circuitry to facilitate zero-voltage-switching of the high side or floating transistor and providing more robust rejection of false triggering. A capacitively coupled differential input edge triggered gate driver provides exceptional immunity to false triggering. The gate drivers may be used in transformer coupled drive circuits using transformers that need only support coupled pulses wide enough to be recognized as an edge by the input circuit.
