SECO-NCD57000-GEVB
NCD57000 mini Evaluation
Board User's Manual
Purpose
This document describes the use and applications for the
NCD57000 gate driver mini board. The board is designed on a two
layer PCB and includes the NCD57000 driver and all the necessary
drive circuitry. 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 configuration. The boards can be considered as
an isolator+driver+TO−247 discrete module.
NCD57000 Description
NCD57000 is a high−current single channel IGBT driver with
internal galvanic isolation, designed for high system efficiency and
reliability in high power applications. Its features include
complementary inputs, open drain FAULT and Ready outputs, active
Miller clamp, accurate UVLOs, DESAT protection, soft turn−off at
DESAT, and separate high and low (OUTH and OUTL) driver outputs
for system design convenience. NCD57000 accommodates both 5 V
and 3.3 V signals on the input side and wide bias voltage range on the
driver side including negative voltage capability. NCD57000 provides
> 5 kVrms (UL1577 rating) galvanic isolation and > 1200 Viorm
(working voltage) capabilities. NCD57000 is available in the
wide−body SOIC−16 package with guaranteed 8 mm creepage
distance between input and output to fulfill reinforced safety
insulation requirements.
