Mitsubishi PSS05S92F6-AG | Compact 600V/5A DIPIPM for High-Efficiency Motor Control
The Mitsubishi PSS05S92F6-AG is a high-performance, compact intelligent power module (IPM) from the DIPIPM™ Ver. 6 series, engineered to simplify and accelerate the design of low-power three-phase motor control systems. By integrating a three-phase inverter power stage with optimized gate drivers and a comprehensive suite of protection circuits, this module offers a robust, all-in-one solution that dramatically reduces design complexity, PCB footprint, and time-to-market.
Application Scenarios and Engineering Value
The PSS05S92F6-AG is not just a component; it's a system-level solution engineered for applications where efficiency, reliability, and space are paramount. Its design directly addresses the core challenges faced by engineers in the following areas:
- Inverter Air Conditioners & Heat Pumps: In modern HVAC systems, the demand for smaller outdoor units and higher energy efficiency ratings (SEER/HSPF) is relentless. The PSS05S92F6-AG's Super mini DIPIPM package allows for a significantly smaller inverter board, while its low-loss IGBTs ensure the system meets stringent energy consumption standards. The integrated protections are key to making IGBTs the linchpin of high-efficiency inverter ACs.
- Variable Speed Fan Motors: For applications in ventilation or appliance cooling, this DIPIPM enables smooth, quiet, and efficient motor operation. The integrated gate driver is perfectly matched to the IGBTs, minimizing switching noise and electrical interference (EMI), which simplifies system-level EMC compliance.
- Home Appliances (Washing Machines, Dryers): The direct-drive motors in modern washing machines and dryers require precise control and extreme reliability. The PSS05S92F6-AG provides this with its robust short-circuit (SC) and undervoltage (UV) protection, safeguarding the system against common grid faults and extending the appliance's lifespan.
Technical Deep Dive: The DIPIPM Advantage
Two core engineering principles set the PSS05S92F6-AG apart from discrete component solutions: its intelligent integration and optimized high-side drive topology.
1. Integrated Gate Drive and Protection Intelligence
Moving beyond simple power switching, this module incorporates high-voltage and low-voltage ICs (HVIC and LVIC) on the same substrate. This colocation delivers critical advantages:
- Matched Gate Driving: The gate drive circuit is factory-tuned to the specific characteristics of the internal IGBTs, ensuring optimal switching performance without the risk of parasitic oscillations or excessive ringing.
- Real-time Protection: It features built-in protection for short-circuit (SC), control supply undervoltage (UV), and over-temperature (OT). If a fault is detected, the module sends a fault signal (Fo) and safely shuts down the IGBTs, preventing catastrophic failure. This level of integrated IGBT failure analysis and prevention is a significant reliability enhancement.
2. Simplified Bootstrap Circuitry
Powering the high-side gate drivers in a three-phase bridge is a classic design challenge. The PSS05S92F6-AG integrates high-speed, low-forward-voltage bootstrap diodes and current-limiting resistors for each phase. This design choice, detailed in Mitsubishi DIPIPM™ application notes, means engineers only need to add three external bootstrap capacitors to create a reliable floating power supply for the high-side drivers. This drastically reduces the bill of materials (BOM), eliminates complex isolated power supply designs, and saves critical board space.

Engineer's FAQ
What are the primary considerations for thermal management with the Super mini DIPIPM package?
Due to its compact size, effective thermal management is crucial. The low thermal resistance (Rth(j-c)) facilitates heat transfer, but designers must ensure a low-resistance thermal path to the ambient. This involves selecting an appropriately sized heatsink and using a high-quality thermal interface material (TIM) to minimize contact resistance between the module's base and the heatsink. Always calculate the maximum expected power dissipation under worst-case load conditions to verify the junction temperature remains below the 150°C maximum rating.
How does the PSS05S92F6-AG simplify the control interface compared to a discrete solution?
The module simplifies the interface down to low-voltage logic signals. It requires only six PWM control inputs (typically from a microcontroller) and a fault output pin. All the complexity of level-shifting, dead-time insertion, and high-current gate driving is handled internally. This "logic-in, power-out" design frees the MCU from critical timing tasks and allows designers to focus on the application-level control algorithm.
