The DIODES DGD0579U, High-side/Low-side gate driver with Integrated Bootstrap Diode is used to optimally drive the gate of MOSFETs. Below is an example application using DGD0579U with MOSFETs to make three Half-bridge circuits used to drive a BLDC motor. The DGD0579U is also well-suited to low voltage power supplies due to its high-speed performance. In this document, the important parameters needed to design in the DGD0579U are discussed. Main sections are bootstrap capacitor selection, gate driver component selection, decoupling capacitor discussion, and PCB layout suggestions.

The DGD0215/16 and DGD0211C are High-Speed, Low-Side Gate Drivers, capable of source current of 1.9A and sink current of 1.8A. Low-Side Gate Drivers will optimally charge the gate of MOSFETs or IGBTs in a ground-based configuration.

The DGD2101M, High-side/Low-side gate driver is used to optimally drive the gate of MOSFETs or IGBTs. Below (Figure 1) is an example application using DGD2101M with MOSFETs to make three Half-bridge circuits used to drive a three phase motor. Typical motor applications are AC Induction motors, PMSMs, and BLDC motors. DGD2101M can also be used in power supplies. In this document, the important parameters needed to design in the DGD2101M are discussed. Main sections are bootstrap resistor, diode, and capacitor selection, gate driver component selection, decoupling capacitor discussion, and PCB layout suggestions.
