NCP51752BDDR2G中文资料安森美半导体数据手册PDF规格书

The NCP51752 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 NCP51752 offers short and matched

propagation delays. For improved reliability, dV/dt immunity and

even faster turn−off, the NCP51752 has an innovative embedded

negative bias rail mechanism. The NCP51752 offers other important

protection function such as independent under−voltage lockout for

both−side driver. Its Vcc UVLO threshold is referenced to GND2 for

true UVLO regardless of VEE level. The NCP51752 is available in a

4 mm SOIC−8 package and can support isolation voltage up to

3.75 kVRMS.
