NCD5703A, NCD5703B,
NCD5703C
High Current IGBT Gate
Drivers
The NCD5703A, NCD5703B and NCD5703C are high−current,
high−performance stand−alone IGBT drivers for high power
applications that include solar inverters, motor control and
uninterruptible power supplies. The devices offer a cost−effective
solution by eliminating external output buffer. Devices protection
features include accurate Under−voltage−lockout (UVLO),
desaturation protection (DESAT) and Active open−drain FAULT
output. The drivers also feature an accurate 5.0 V output. The drivers
are designed to accommodate a wide voltage range of bias supplies
including unipolar and NCD5703B even bipolar voltages.
Depending on the pin configuration the devices also include Active
Miller Clamp (NCD5703A) and separate high and low (V
OH
and V
OL
)
driver outputs for system design convenience (NCD5703C).
All three available pin configuration variants have 8−pin SOIC
package.
