onsemi / Fairchild FAN7393A Half-Bridge Gate-Drive IC

onsemi / Fairchild FAN7393A Half-Bridge Gate-Drive IC features shutdown and programmable dead-time control functions that can drive high-speed MOSFETs and Isolated Gate Bridge Transistors (IGBTs) operating up to +600V. This IC has a buffered output stage with all NMOS transistors designed for high-pulse-current driving capability and minimum cross-conduction. The onsemi / Fairchild FAN7393A Half-Bridge Gate-Drive IC has a high-current and low-output voltage drop. This feature makes this device suitable for diverse half- and full-bridge inverters, motor drive inverters, switching mode power supplies, induction heating, and high-power DC-DC converter applications.

Features

  • Floating Channel for Bootstrap Operation to +600V
  • Typically 2.5A/2.5A Sourcing/Sinking Current Driving Capability
  • Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VBS=15V
  • High-Side Output in Phase of IN Input Signal
  • 3.3V and 5V Input Logic Compatible
  • Matched Propagation Delay for Both Channels
  • Built-in Shutdown Function
  • Built-in UVLO Functions for Both Channels
  • Internal 400ns Minimum Dead Time at RDT=0Ω
  • Programmable Turn-On Delay Control (Dead-Time)

Applications

  • High-Speed Power MOSFET and IGBT Gate Drivers
  • Induction Heating
  • High-Power DC-DC Converters
  • Synchronous Step-Down Converters
  • Motor Drive Inverters
