Introduction

AI Translation

This device is a compact gate driver that serves as an excellent replacement for NPN and PNP discrete driver (buffer circuit) solutions. The driver is suitable for MOSFETs, IGBTs, and emerging wide-bandgap power devices such as GaN. It is designed for high-speed applications. Its asymmetric 4A peak source current and 8A peak sink current enhance immunity to parasitic Miller turn-on. Features include wide input hysteresis and negative input voltage handling capability, providing enhanced immunity to transient noise.

Features

AI Translation
  • 4.5 to 18V single-supply range
  • Output held low during VDD undervoltage lockout
  • TTL and CMOS compatible input logic thresholds
  • Output designed to remain low when input pins are floating
  • Fast rise and fall times (9ns and 7ns typical, respectively)
  • Fast propagation delay (13ns typical)
  • Split-output configuration
  • Strong sink current capability for enhanced Miller turn-on immunity
  • Input pins tolerant to 5V below GND pin
  • Compact package: SOT23-5

Applications

AI Translation
  • DC-DC converters
  • Desktop PC power supplies
  • Switching mode power supplies
  • Companion gate drivers for digital power controllers
  • Gate drivers for emerging wide-bandgap power devices (e.g., GaN)
