产品概述

3 A, 5.7 kV single-channel flexible isolated gate driver with active Miller clamp, adjustable DESAT and Soft-off. UL 1577 & VDE 0884-11 certified

EiceDRIVER™ Enhancedsingle-channel highly flexibleisolated gate driverwith ±3 A typical sinking and sourcing peak output current in small space-saving DSO-16 fine pitch wide-body package with large creepage distance (>8 mm) forIGBTs,MOSFETsandSiC MOSFETs.

1ED3431MC12M belongs to the EiceDRIVER™ Enhanced 1ED34xx family (X3 analog family) – single-channelisolated gate driver with adjustable DESAT and soft-off. Suitable forIGBTs,MOSFETsandSiC MOSFETs. 1ED3431 offers high configurability with DESAT (adjustable filter time), and soft-off (adjustable current level), through external resistor from input side (ADJA and ADJB pin). The driver IC also offers separate output, active Miller clamp, Fault, and over temperature shutdown.

1ED3830(X3 Digital) version available, offer 27 configuration registers accessible via I2C.

特征描述

  • Flexible EiceDRIVER™ Enhanced single channel isolated gate driver 1ED34xx family (X3 Analog family)
  • For use with 650 V/1200 V/1700 V/2300 V IGBTs, Si and SiC MOSFETs
  • 2300 V functional offset voltage capable for selected applications
  • ±3 A typical sinking and sourcing peak output current
  • 40 V absolute maximum output supply voltage
  • Separate source and sink outputs
  • Active Miller clamp
  • Precise VCEsat detection (DESAT) with fault output
  • IGBT soft turn-off after desaturation detection
  • Parameter adjustment from input side:
  • Adjustable DESAT filter time with ADJB pin
  • Adjustable soft-off current level with ADJA pin
  • FLT and RDY status signaling to µController
  • 11 V/12 V undervoltage lockout (UVLO) protection with hysteresis

优势

  • Over-temperature shut down at 160 °C (±10 °C)
  • Tight IC-to-IC propagation delay matching (30 ns max.)
  • High common-mode transient immunity CMTI >200 kV/μs
  • Suitable for operation at high ambient temperature up to 125 °C
  • Small space-saving DSO-16 fine pitch wide-body package with large creepage distance (>8 mm)
  • UL 1577 VISO = 6.84 kV (rms) for 1 s, 5.7 kV (rms) for 1 min
  • IEC 60747-17/VDE 0884-11 with VIORM = 1767 V (peak, reinforced)

  • Enable fast design cycles and the best-in-class DESAT accuracythanks to low external component count and the adjustable DESAT with Soft-off

  • The precise threshold and timings, combined with UL 1577 and IEC 60747-17/VDE 0884-11 certifications enable superior application safety

  • Perfect fit for all applications requiring a reliable DESAT protection, benefiting from an active Miller clamp and preferring small PCB space requirements
