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 supports MOSFETs, IGBTs, and emerging wide-bandgap power devices such as GaN, making it suitable for high-speed applications. Its asymmetric 4-A peak source current and 8-A peak sink current enhance immunity to parasitic Miller turn-on. Features including wide input hysteresis and negative input voltage handling capability improve transient noise immunity.

Features

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

Applications

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