Mitsubishi PS21353-G DIP-IPM | Streamlining Low-Power Motor Control
The Mitsubishi PS21353-G is not just a component; it's a complete power stage solution engineered for modern, compact, and highly reliable low-power motor drive systems. As part of Mitsubishi's renowned DIP-IPM family, this Intelligent Power Module (IPM) integrates six IGBTs, freewheeling diodes, and the critical gate drive and protection circuitry into a single, compact dual-in-line package. It is the definitive choice for engineers developing systems for home appliances, small-scale industrial automation, and servo drives where efficiency, board space, and accelerated time-to-market are paramount.
Deep Dive: Integrated Intelligence and Protection
- All-in-One Gate Drive & Protection Circuitry: The core value of the PS21353-G lies in its integration. It incorporates dedicated high-voltage ICs (HVICs) that provide optimized gate signals for the internal IGBTs, along with a suite of essential protection functions. This includes under-voltage lockout (UV) for both high-side and low-side supplies and short-circuit (SC) protection.
Application Value: This high level of integration dramatically simplifies your PCB layout, reduces component count, and eliminates the complex and error-prone process of designing and tuning a discrete gate driver circuit. You achieve higher system reliability and a significantly shorter design cycle. - Optimized Thermal Performance in a Compact DIP Package: The PS21353-G is engineered with a low thermal resistance package. The internal structure is meticulously designed to ensure an efficient thermal path from the IGBT and diode chips to the module's case.
Application Value: This superior thermal management allows for smaller heatsinks or even heatsink-less operation in certain low-load conditions, directly reducing system size, weight, and bill-of-materials (BOM) cost. It ensures stable operation and enhances the long-term lifespan of your end product.
Where the PS21353-G Excels: Application-Specific Advantages
- Home Appliances (Washing Machines, Air Conditioners): In this cost-sensitive sector, the PS21353-G reduces BOM cost and assembly complexity. Its integrated protections safeguard the drive against common grid fluctuations and motor faults, improving the appliance's durability and reducing warranty claims.
- Small Industrial Pumps and Fans: For compact industrial equipment, board space is a premium. The DIP package of the Mitsubishi PS21353-G is ideal. Its inherent robustness and integrated fault detection provide the reliability needed for continuous operation in demanding factory environments.
- Low-Power Servo Drives: Precision is key in servo control. The matched characteristics of the integrated driver and IGBTs inside the PS21353-G ensure consistent, low-latency switching performance, which is critical for accurate position and speed control loops.

Why Choose the PS21353-G IPM Over a Discrete Solution?
Designers often face a choice: use an integrated IPM like the PS21353-G or build a power stage with discrete IGBTs, diodes, and a gate driver IC. While a discrete approach offers granular component selection, the PS21353-G provides compelling system-level benefits. It eliminates concerns about gate drive layout, parasitic inductance, and component matching. For projects prioritizing development speed, reliability, and a compact footprint in the sub-1kW power range, this IPM is almost always the more efficient and robust choice.

Frequently Asked Questions
- How critical is heatsinking for the PS21353-G?
While its thermal performance is excellent, a heatsink is typically required for applications running near the rated current. The necessity and size depend on the switching frequency, load current, and ambient temperature. Always ensure a good thermal interface with quality thermal grease for optimal heat dissipation. - How does the short-circuit protection work?
The module uses an external sense resistor on the DC-bus negative rail to detect an overcurrent condition. When the voltage across this resistor exceeds a predefined threshold, the internal logic triggers a fault signal and safely shuts down all six IGBTs to prevent catastrophic failure.
By integrating key power and control functions, the Mitsubishi PS21353-G empowers engineers to create more efficient, compact, and reliable motor control systems with greater confidence and speed.
