Mitsubishi PS21564-P | Compact DIPIPM™ for High-Efficiency Motor Control
The Mitsubishi PS21564-P is an advanced DIPIPM™ (Dual-In-Line Package Intelligent Power Module) engineered to simplify and accelerate the development of compact, low-power inverter applications. It represents a paradigm shift from complex discrete designs to a highly reliable, integrated solution, making it a cornerstone for modern motor control systems.
- Brand: Mitsubishi Electric
- Model: PS21564-P
- Core Function: 600V / 5A three-phase IPM (Intelligent Power Module)
- Key Benefit: Dramatically reduces design complexity and board space by integrating power stages, gate drivers, and comprehensive protection circuits.
- Typical Applications: Home appliances (air conditioners, washing machines), small industrial pumps and fans, and low-power servo drives.
The Power of Integration: Inside the DIPIPM™ Architecture
The true value of the PS21564-P lies in its sophisticated level of integration. It's not just an IGBT module; it's a complete power conversion subsystem in a single compact package. This approach directly addresses the engineering challenges of miniaturization and reliability.

All-in-One Power Stage and Drive Circuitry
The module houses three-phase IGBTs, freewheeling diodes, high-voltage ICs (HVICs), and low-voltage ICs (LVICs). It also includes built-in bootstrap diodes and resistors for the high-side gate drive supply. This eliminates the need for dozens of external components, simplifying PCB layout, reducing parasitic inductance, and minimizing potential EMI issues. The result is a cleaner, more robust design cycle and a faster path to market.

Built-in Intelligent Protection for Unmatched Reliability
The PS21564-P integrates a suite of critical protection functions. This includes short-circuit (SC) protection, control supply under-voltage (UV) lockout, and an analog temperature output (VOT) for over-temperature (OT) protection. By embedding these safety mechanisms directly into the module, it ensures a faster and more reliable response to fault conditions than discrete implementations, safeguarding the motor and the drive itself.
Solving Real-World Challenges: PS21564-P in Action
This module excels in applications where space, efficiency, and reliability are non-negotiable. Its design philosophy provides tangible benefits across various industries.
- Compact Home Appliances: In air conditioners and washing machines, the small footprint of the Mitsubishi PS21564-P enables designers to create smaller, quieter, and more energy-efficient products that meet stringent consumer demands and regulatory standards.
- Industrial Automation: For small industrial pumps, fans, and conveyor belts, the module's high reliability and integrated protection reduce system downtime and maintenance costs, a critical factor in maintaining productivity in factory environments.
- Precision Servo Drives: The integrated gate driver and optimized internal layout ensure clean and efficient switching. This is vital for the precise torque and speed control required in entry-level robotics and robotic servo drives, where performance cannot be compromised.

Selection Insight: PS21564-P vs. Discrete Solutions
Engineers often face a choice between a fully integrated IPM like the PS21564-P and a design using discrete IGBTs and drivers. While a discrete approach offers granular component selection, it introduces significant complexity in gate drive design, protection circuitry implementation, and thermal management. The PS21564-P abstracts this complexity away, offering a pre-validated, highly reliable solution that is ideal for teams looking to minimize development risk and accelerate production for applications under 2kW.
Frequently Asked Questions
- What is the primary benefit of the integrated bootstrap circuit?
It greatly simplifies the power supply design for the high-side gate drivers. By including the diodes and current-limiting resistors, it reduces external component count, saves valuable PCB space, and lowers the bill of materials (BOM) cost. - How can I use the analog temperature output (VOT)?
The VOT pin provides a voltage signal that is proportional to the module's internal substrate temperature. This allows the system's microcontroller (MCU) to actively monitor thermals, implement an over-temperature shutdown, or perform intelligent power throttling to prevent failure and extend the system's operational lifespan.
