NCD5701A, NCD5701B, NCD5701C High Current IGBT Gate Drivers The NCD5701A, NCD5701B and NCD5701C are highcurrent, highperformance standalone 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 Undervoltagelockout (UVLO), 8 desaturation protection (DESAT) and Active Low FAULT output. The 1 NCD5701X drivers also feature an accurate 5.0 V output. The drivers are designed SOIC8 ALYW to accommodate a wide voltage range of bias supplies including D SUFFIX CASE 751 unipolar and NCD5701B even bipolar voltages. 1 Depending on the pin configuration the devices also include Active NCD5701 = Specific Device Code Miller Clamp (NCD5701A) and separate high and low (V and V ) OH OL X = A, B or C driver outputs for system design convenience (NCD5701C).
