NCD5701A, NCD5701B,
NCD5701C
High Current IGBT Gate
Drivers
The NCD5701A, NCD5701B and NCD5701C 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 Low 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 NCD5701B even bipolar voltages.
Depending on the pin configuration the devices also include Active
Miller Clamp (NCD5701A) and separate high and low (V
OH
and V
OL
)
driver outputs for system design convenience (NCD5701C).
All three available pin configuration variants have 8−pin SOIC
package.
