NCD570x High-Current IGBT Gate Drivers

ON Semiconductor's NCD570x family of devices are high-current, high-performance, stand-alone IGBT drivers for high power applications that include solar inverters, motor control, and uninterruptable power supplies. The devices offer a cost-effective solution by eliminating many external components. Device protection features include active Miller clamp, accurate UVLO, EN input, DESAT protection, and active low FAULT output. The drivers also feature an accurate 5.0 V output. The drivers are designed to accommodate a wide voltage range of bias supplies including unipolar and bipolar voltages.

Features
  • High current output (+4.0/-6.0 A) at IGBT Miller plateau voltages
  • Reduced switching losses and short switching times
  • Low VOH and VOL
  • Full enhancement of IGBT active Miller clamp
  • Prevents spurious gate turn-on DESAT protection with programmable delay
  • Enhanced programmable protection
Applications
  • DC-AC inverter
  • Battery charger
  • PFC
  • Motor driver
  • Solar inverters
  • Uninterruptible power supplies (UPS)
  • Motor control
