Beschreibung

This document analyzes two methods to increase the drive current from integrated gate-driver ICs. The performance of both the methods is compared by building boards and testing them at various conditions.These circuits are discussed in further detail in subsequent sections.

Eigenschaften

  • Designed for reliable and rugged applications– Wide input voltage range of 4.5 V to 65 V– Robust solution with only one component crossing the isolation barrier– ±1.5% total output regulation accuracy– Optional VOUT temperature compensation– 6-ms internal or programmable soft start– Input UVLO and thermal shutdown protection– Hiccup-mode overcurrent fault protection– –40°C to +150°C junction temperature range

Typische Anwendungen

  • Multi-output rails for analog input modules
  • Isolated field transmitters and field actuators
  • Motor drive: IGBT gate drive supplies
  • Building automation HVAC systems
