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.
