NCV5703A, NCV5703B, NCV5703C High Current IGBT Gate Drivers The NCV5703A, NCV5703B and NCV5703C 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 solution by eliminating external output buffer. Devices protection MARKING features include accurate Under voltage lockout (UVLO), DIAGRAM 8 8 desaturation protection (DESAT) and Active opendrain FAULT 1 output. The drivers also feature an accurate 5.0 V output. The drivers NCV5703X SOIC8 are designed to accommodate a wide voltage range of bias supplies ALYW D SUFFIX including unipolar and NCV5703B even bipolar voltages. CASE 751 Depending on the pin configuration the devices also include Active 1 Miller Clamp (NCV5703A) and separate high and low (V and V ) OH OL NCV5703 = Specific Device Code driver outputs for system design convenience (NCV5703C).
