Abstract:
1. A power circuit comprising: a driver output; a MOSFET; and circuitry to ensure a positive drive to a gate of the MOSFET when the driver output goes to a first signal level, and to ensure a low negative drive to the gate of the MOSFET when the driver output goes to a second signal level, wherein the circuitry includes: a PNP bipolar transistor; a first capacitor coupled between the driver output and a base of the PNP bipolar transistor, wherein the capacitor drives the base of the PNP bipolar transistor; a diode coupled to the gate of the MOSFET; and a second capacitor coupled between the driver output and the gate of the MOSFET, wherein the second capacitor is coupled in parallel with the diode.
