9 The bipolar transistorsprovide maximum gate drive current during the powerMOSFET s switching transition and the CMOS transistorsare used to pull the output to the rails at the end of theswitching transition. TrueDrive technology delivers high current at where it is needed most at the MOSFETM iller plateau region thresholds, and provides switchingefficiency gains. PowerMOSFETVDDPGNDOUTINIn a typical switching cycle of a power MOSFET , the critical region that affects theswitching losses is the Miller Plateau. The switching speed is dependent on sink andsink current capability of the output driver, while the MOSFET gate-source voltage isbetween the threshold level and Miller plateau voltage.

10 MOSFET Drivers usingTrueDrive Technology, however, can provide efficient current sourcing and sinkingwhere it is needed most at the Miller plateau region. Step 1 corresponds to turn-on/turn-off delay. Step 2 + Step 3 indicate switching time. Step
