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.
The NCP51152 offers other important protection function such as
independent under−voltage lockout for both−side driver.
