Product Details

The SCALE-iFlex LT NTC is a family of dual plug-and-play gate drivers for driving half-bridge power modules with Negative Temperature Coefficient (NTC) temperature sensing via electrical interface. It enables easy paralleling of power modules providing high flexibility and system scalability.

The SCALE-iFlex LT NTC gate driver family consists of an Isolated Master Control (IMC) unit that supports up to four Module Adapted Gate Drivers (MAGs) together with a cable set.

The IMC operates power modules that have a rated blocking voltage of up to 3300 V. The MAGs are matched to the specific power modules from a variety of suppliers.

Highly Integrated, Compact Footprint

  • Ready-to-use gate driver solution for power modules up to 3300 V blocking voltage
  • Dual channel gate driver
  • Flexible input supply voltage with 15 VDC or 24 VDC
  • Up to 5.5 W output power per channel at maximum ambient temperature
  • Electrical interface
  • -40 °C to 85 °C operating ambient temperature

Protection / Safety Features

  • Supporting short circuit detection and advance active clamping of the Module Adapted Gate Driver
  • Undervoltage lock-out (UVLO) protection for primary-side (low-voltage) and secondary-side (high-voltage)
  • NTC temperature sensing with reinforced isolated output signal (PWM-coded signal)
  • Applied double sided conformal coating

Comprehensive Safety and Regulatory Compliance

  • 100% production test for partial discharge and HIPOT test of transformer
  • Creepage and clearance distances between primary and secondary sides meets IEC 61800-5-1 reinforced isolation requirements
  • RoHS compliant
