The Mitsubishi PS21964-4S is a dual-in-line package intelligent power module that integrates a transfer-mold type insulated design suitable for 600V/15A applications. This component combines low-loss 5th generation IGBT inverter bridge technology dedicated to three-phase DC-to-AC power conversion with open emitter configuration. It is designed with embedded drive circuits, high voltage high-speed level shifting, under-voltage protection for both upper and lower leg IGBTs, short circuit protection for lower-leg IGBTs, and system control functionalities into a compact package. The module supports fault signaling corresponding to short circuit faults in the lower-leg IGBT or under-voltage conditions, offering an integrated solution for AC100V~200V inverter drive applications in small power motor controls. With its UL approval (Yellow Card No. E80276) and featuring an input interface compatible with 3V and 5V lines (High Active), the PS21964-4S is engineered to cater to a broad range of industrial applications demanding reliable and efficient power conversion and control.
