NCV5703A, NCV5703B,
NCV5703C
High Current IGBT Gate
Drivers
The NCV5703A, NCV5703B and NCV5703C 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 NCV5703B even bipolar voltages.
