NCD5703A, NCD5703B, NCD5703C High Current IGBT Gate Drivers The NCD5703A, NCD5703B and NCD5703C are highcurrent, high performance stand alone IGBT drivers for high power www.onsemi.com applications that include solar inverters, motor control and uninterruptible power supplies. The devices offer a costeffective MARKING solution by eliminating external output buffer. Devices protection DIAGRAM 8 features include accurate Under voltage lockout (UVLO), 8 desaturation protection (DESAT) and Active opendrain FAULT 1 NCD5703X output. The drivers also feature an accurate 5.0 V output. The drivers SOIC8 ALYW are designed to accommodate a wide voltage range of bias supplies D SUFFIX CASE 751 including unipolar and NCD5703B even bipolar voltages. 1 Depending on the pin configuration the devices also include Active NCD5703 = Specific Device Code Miller Clamp (NCD5703A) and separate high and low (V and V ) OH OL X = A, B or C driver outputs for system design convenience (NCD5703C).
