NCP81075 Dual MOSFET Gate Driver
onsemi NCP81075 Dual MOSFET Gate Driver is designed to drive the gates of both High Side and Low Side power MOSFETs in a synchronous buck converter. The NCP81075 integrates a driver IC and an on-chip bootstrap diode, eliminating the need for an external discrete diode. A high floating top driver design accommodates HB voltage as high as 180V. The Low Side and High Side are independently controlled and match to 4ns between the turn−on and turn−off of each other. Independent Under−Voltage lockout is provided for the high-side and low-side driver, forcing the output low when the drive voltage is below a specific threshold. The NCP81075 is offered in SOIC-8, DFN8, and WDFN10 packages for design flexibility and is Pb−Free, Halogen-Free/BFR-Free, and RoHS-Compliant.
