IRS2336D International Rectifier Corp., IRS2336D Datasheet - Page 18

• Manufacturer Part Number: IRS2336D
• Description: High Voltage 3 Phase Gate Driver Ic
• Manufacturer: International Rectifier Corp.

Application Information and Additional Details
Information regarding the following topics are included as subsections within this section of the datasheet.
IGBT/MOSFET Gate Drive
The IRS2336xD HVICs are designed to drive up to six MOSFET or IGBT power devices. Figures 1 and 2 illustrate
several parameters associated with the gate drive functionality of the HVIC. The output current of the HVIC, used to
drive the gate of the power switch, is defined as I
defined as V
generically called V
