PS11016

Overview

The Mitsubishi PS11016 is a flat-base type insulated Application Specific Intelligent Power Module (ASIPM) integrating a 3-phase IGBT inverter bridge with dynamic braking. It features integrated drive, protection, and system control functions for P-side and N-side IGBTs, including short-circuit protection, under/over-voltage protection, and over-temperature protection. The module supports an output current capability of 11.0A rms at 100% load and 16.5A rms at 150% overload. It utilizes a single drive-power-supply bootstrap scheme and provides fault signaling via open-collector outputs.

Procurement Notes

Verify the manufacturer designation as Mitsubishi Semiconductor on official documentation. Confirm the specific part number PS11016 matches the required flat-base insulated package configuration. Ensure compatibility with the specified 15V control supply voltage and 5V logic interface requirements before integration into the design.

Selection Notes

Select this module for applications requiring a compact solution combining power switching with intelligent control. Consider the thermal resistance characteristics and the need for adequate heatsinking given the flat-base mounting style. Evaluate the insulation voltage rating against the system's DC bus requirements to ensure safe operation within the specified temperature range.

Part Context

This component belongs to the ASIPM category, designed to simplify inverter designs by embedding gate drivers and protection circuits directly with the power devices. It represents a consolidated approach to motor control hardware, reducing the component count and board space typically required for discrete driver and protection implementations.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative modules from other manufacturers.

FAQ

How does the module handle arm shoot-through?

The module includes an input inter-lock sensing circuit that cuts off both upper and lower IGBTs of a mal-triggered phase if simultaneous LOW level signals are detected, outputting an FO signal.

What is the function of the CL output?

The CL output provides a warning signal whenever the arm current exceeds the limit, operating on a pulse-by-pulse scheme and resetting automatically with the next input signal.

Can the module be driven directly by a CPU?

Yes, due to the integrated photo-coupler inside the module, direct coupling to a CPU without external opto or transformer isolation is possible.
