Description

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.
