Circuit for driving two power mosfets in a half-bridge configuration

摘要

A driver circuit and method for alternately driving first and second power transistors is provided. The driver circuit includes shoot- through reduction circuitry for monitoring the gate-to-source voltages of the two power transistors so as to inhibit the turning-ON of each power transistor until the gate-to-source voltage of the other power transistor has fallen to a voltage level indicative of the other transistor being OFF. Additionally, the driver circuit includes a circuit to prevent transient signals from said power transistors from affecting the operation of the driver circuit.
