Key Features

  • Integrates the IGBT, FRD, pre-driver and protection circuits.
  • Built-in thermal protection, 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.

Ordering number : EN*A0483 STK621-041, STK621-041A-E Thick-Film Hybrid IC Air Conditioner Three-Phase Compressor Motor Driver IMST Inverter Power Hybrid IC Overview The STK621-041 and STK621-041A-E are STK621-000 series products that use a miniature SIP package. These threephase motor driver hybrid ICs integrate the power main circuit block and peripheral circuits needed for inverter control into a single package. The upper-side control power supply can be provided by a bootstrap circuit, making it possible to configure the control power supply with a single power supply (VD4 = 15V).
