SECO-NCD5700-GEVB
NCD5700 mini Evaluation
Board User's Manual
Purpose
This document describes the use and applications for the NCD5700
gate driver mini board. The board is designed on a two layer PCB and
includes the NCD5700 driver and all the necessary drive circuitry
including isolation as can be seen in Figure 3. The board also includes
ability to solder any MOSFET or SiC MOSFET in a TO−247 high
voltage package and compatibility with SECO−GDBB−GEVB
baseboard for out−of−the−box evaluation. The board does not include
a power stage and is generic from the point of view that it is not
optimized to any particular topology. It can be used in any low−side or
high−side power switching application. For bridge configurations two
or more of these boards can be configured in a totem pole type drive
c o n f i g u r a t i o n . T h e b o a r d s c a n b e c o n s i d e r e d a s a n
isolator+driver+TO−247 discrete module.
NCD5700 Description
The NCD5700 is a high−current, high−performance stand−alone
IGBT driver for high power applications that include solar inverters,
motor control and uninterruptable power supplies. The device offers a
cost−effective solution by eliminating many external components.
Device protection features include Active Miller Clamp, accurate
UVLO, EN input, DESAT protection and Active Low FAULT
output. The driver also features an accurate 5.0 V output and separate
high and low (VOH and VOL) driver outputs for system design
convenience. The driver is designed to accommodate a wide voltage
range of bias supplies including unipolar and bipolar voltages. It is
available in a 16−pin SOIC package. The simplified block diagram is
shown in Figure 4.
