IGBT gate drivers, high-current, stand-alone, non-inverting
The NCD5703 series is a set of high-current, high-performance stand-alone IGBT drivers for medium-to-high power applications that include induction heating, welding, solar inverters, motor control and uninterruptable power supplies. The devices offer a cost-effective solution by eliminating many external components. Device protection features include Active Miller Clamp (for NCD5703A), accurate UVLO, DESAT protection and Active Low FAULT output. The drivers also feature an accurate 5.0 V output (for all versions) and separate high and low (VOH and VOL) driver outputs (for NCD5703C only) for system design convenience. The drivers are designed to accommodate a wide voltage range of unipolar bias supplies (and bipolar bias supplies for NCD5703B).All versions are available in an 8-pin SOIC package.
