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
and
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.

RIC74424EVAL1 user guide Open loop dual output gate driver with R9 FETs Introduction Introduction RIC74424 is a high speed, non-inverting, dual channel low side gate driver. RIC74424EVAL1 comes pre- populated with IRHNJ9A7130 (100 V, 35 A in SMD-0.5 package) and IRHNS9A7064 (60V, 100 A in SupIR-SMD package). -
Page 5: Functional Description
RIC74424EVAL1 user guide Open loop dual output gate driver with R9 FETs Functional description Functional description Bias power For proper operation, an external bias power supply is required for VS. The drive voltage of RIC74424 is set by the voltage on VS. It is recommended to keep VS within the recommended operating range for RIC74424, which is 5 V to 20 V. -
Page 6: Power Stage
RIC74424EVAL1 user guide Open loop dual output gate driver with R9 FETs Functional description Attention: Gate to source test points introduce small amounts of parasitic inductance, which increases measured voltage overshoot and ringing. For critical measurements of amplitude and settling time, it is recommended to place oscilloscope probes directly on gate and source pins of the FET. -
Page 7: Optional Heat Sink
RIC74424EVAL1 user guide Open loop dual output gate driver with R9 FETs Functional description Test points for drain to source voltage (V ) measurements are provided for accurate measurements. It is recommended that ground spring connections are used with oscilloscope probes to reduce measurement error. -
