Abstract
A driver circuit for driving top and bottom power transistors stacked between two supply terminals is provided. The driver circuit includes shoot-through reduction means 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 which can utilize a bootstrap capacitor for providing enhanced voltages to drive the top power transistor, also includes a bootstrap capacitor recharge means to monitor the output voltage of the circuit so as to inhibit the turning-ON of the top power transistor until the bootstrap capacitor has had sufficient time to recharge.
