PS22A78-E

The Mitsubishi Electric PS22A78-E is an insulated transfer molding type DIPIPM (Dual In-line Package Intelligent Power Module) designed for 3-phase DC/AC inverter applications. It boasts a high voltage rating of 1200V and a collector current of 35A, making it suitable for AC 400V class motor control.

This module integrates essential functions for inverter operation, including drive circuits for both the P-side and N-side IGBTs. For the P-side, it provides high voltage, high-speed level shifting and control supply under-voltage (UV) protection. The N-side includes drive circuitry with control supply under-voltage (UV) protection and short circuit (SC) protection, which is achieved by detecting the voltage across an external shunt resistor.

Additional features include fault signaling for SC and UV faults, temperature monitoring via an analog signal output of the LVIC temperature, and a 5V line input interface with a Schmitt trigger receiver circuit. The PS22A78-E is UL Recognized under file E80276.

Applications for this DIPIPM include motor control in appliances such as air conditioners, cloth washers, refrigerators, dishwashers, fans, and pumps. The module is housed in a large, insulated transfer molding package, facilitating efficient heat dissipation and system integration.
