Figure 23 to Figure 26 shows the VDS and VGS waveforms of the low-side and high-side MOSFETs at a total gate current of the DRV8323 (IDRIVE) is set at a 680-mA source and a 2-A sink current. The design uses two FETs in parallel. Therefore, the gate drive current per FET is a 340-mA source and a 1-A sink current. The switching waveforms are captured with a 3.3-Ω gate resistor for each FET. Switching waveforms are clean without any over voltage ringing due to:
