3.75 kVRMS, 4.5-A/9-A isolated single channel gate driver
The NCP51152 is a family of isolated single-channel gate driver with 4.5-A/9-A source and sink peak current respectively. They are designed for fast switching to drive power MOSFETs, and SiC MOSFET power switches. The NCP51152 offers short and matched propagation delays. The NCP51152xA provides a split output that controls the rise and fall times individually. The NCP51152xB has its VCC UVLO referenced to GND2 to get a true UVLO. The NCP51152 is available in a 4 mm SOIC-8 package and can support isolation voltage up to 3.75 kVRMS.
