onsemi NCP51152 Isolated Single Channel Gate Driver

3.75 kVRMS, 4.5-A/9-A

The NCP51152 by onsemi is a family of isolated single-channel gate drivers 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.

Features

  • 4.5-A Peak Source, 9-A Peak Sink Output Current
  • 36 ns Propagation Delay with 5 ns Max Delay Matching
  • 3-V to 20-V Input Supply Voltage
  • 200V/ns dV/dt Immunity

 

  • 3.75 kVRMS Isolation for 1 Minute (per UL1577 Requirements)
  • Separated Outputs (NCP51152xA) or UVLO Referenced to GND2 (NCP51152xB)
  • UVLO options 6-V and 8-V for MOSFET, 12-V and 17-V for SiC
