RIC74424EVAL1 user guide 

Open loop dual output gate driver with R9 FETs 

About this document

RIC74424 is a high speed, dual channel low side gate driver.  This evaluation board is designed to help the user 

evaluate RIC74424 with any other rad hard MOSFET in a SupIR-SMD, SMD-0.5 or SMD-0.5e package.  It comes 
prepopulated with 

IRHNJ9A7130

 and 

IRHNS9A7064

.  This user manual includes overview, setup instructions, 

test results, schematic, printed circuit board layout drawings and bill of material.  More information is available 

on the 

RIC74424 product landing page

RIC74424 datasheet

Intended audience 

This document is intended for engineers who are familiar with MOSFET or IGBT based converters, inverters and 

gate drivers and are looking to evaluate and design RIC74424 into their application.
