STK621-043A-E - Air Conditioner Three-Phase Compressor Motor Driver IMST Inverter Power Hybrid IC

Key Features

  • Built-in overcurrent protection (bus line) and pre-driver supply under voltage protection.
  • Allows CMOS-level input of control signals without an insulating circuit.
  • Use of an upper-side power supply bootstrap circuit (externally set) enables single power supply drive.
  • Built-in circuit for preventing short circuits when both upper and lower inputs are ON at the same time. This prevents arm short circuits due to simultaneous upper and lower phase ON inputs.
