概览

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.
