PS12015-A

Overview

The PS12015-A is a flat-base insulated Application Specific Intelligent Power Module (ASIPM) manufactured by Mitsubishi Semiconductor. It integrates a three-phase IGBT inverter bridge with dynamic braking capability, utilizing third-generation IGBT and diode technologies. The module supports an AC 400V class line output for acoustic noise-less motor control applications. Key electrical ratings include a maximum supply voltage of 800V between P-N terminals and a continuous inverter output current of 4.8A RMS at 100% load, extending to 7.2A RMS for one minute under 150% overload conditions. Thermal resistance from junction to case ranges from 1.9°C/W for the inverter IGBT to 7.3°C/W for the brake FWDi.

Procurement Notes

Verify the specific datasheet revision date, as the provided documentation is dated January 2000. Confirm that the component is sourced from authorized distributors or verified secondary markets due to potential obsolescence. Ensure compatibility with existing thermal management solutions, specifically checking the required mounting torque of 0.78 to 1.27 N·m for the M3.5 screws. Validate that the 5V CMOS/TTL compatible input interface matches the host controller's logic levels.

Selection Notes

Select this module for designs requiring a compact, insulated solution for three-phase motor drives up to 1.5kW. It is suitable where space constraints prevent discrete driver and protection circuit implementation. The integrated bootstrap scheme simplifies single-drive power supply requirements. Engineers must account for the specific thermal resistance values when designing heatsinks, particularly for the brake circuit components which exhibit higher thermal resistance compared to the main inverter legs.

Part Context

This component belongs to the Mitsubishi Semiconductor ASIPM family, designed to simplify the development of intelligent power systems. It combines power switching elements with sophisticated control logic on a single insulated substrate. The flat-base type construction facilitates direct mounting to heat sinks, while the insulation rating ensures safety isolation between the power terminals and the base plate. This integration reduces board space and minimizes parasitic inductance associated with external wiring.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Replacement requires matching the mechanical footprint, pinout configuration, and electrical ratings of the original design.

FAQ

How does the module handle arm shoot-through?

The module includes an input interlock sensing circuit that blocks both upper and lower IGBTs if simultaneous low-level inputs are detected. This triggers a fault output (FO1) and latches the protection until the next valid input edge resets the circuit.

What is the function of the CL terminal?

The CL terminal provides a current-limit warning signal. It outputs a pulse-by-pulse warning whenever the arm current exceeds the specified limit level, allowing for overload detection without triggering immediate shutdown.

Can the module be driven directly by a CPU?

Yes, the module integrates internal photo-couplers, allowing direct coupling to a CPU without external optical or transformer isolation. The inputs are compatible with 5V CMOS/TTL logic levels.
