CGD15SG00D2 Introduction
The purpose of this application note is to demonstrate the design of an isolated gate driver (Cree Part Number: CGD15SG00D2) tailored for Cree’s 3rd Generation (C3MTM) Silicon Carbide (SiC) Metal Oxide Semiconductor Field-Effect Transistor (MOSFET).
CGD15SG00D2 Features
· Creepage enhancing groove between the logic side and the power side of the printed circuit
board (PCB)
· 2W isolated power supply that enables the operation of larger MOSFETs at higher frequencies
· 5000VAC isolation rated optocoupler
· Separate gate turn-on and gate turn-off resistors with a dedicated diode which allow user
friendly optimization of both turn-on and turn-off signals
· Common mode inductor on logic power input for enhanced electro-magnetic interference
(EMI) immunity
· 9mm creepage enhancing slot between primary and secondary circuits
