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.
