IM241M6S1JALMA1

Overview

The Infineon IM241M6S1JALMA1 is a CIPOS™ Micro intelligent power module featuring a 600 V reverse conducting IGBT and integrated gate drivers. It provides a 3-phase open emitter inverter topology with a 4 A collector current rating. The SOP 29x12 package includes an isolated 2000 VRMS interface, built-in NTC thermistor for thermal monitoring, and programmable fault clear functionality via the RFE pin.

Feature Summary

• Integrates reverse conducting IGBT technology with rugged half-bridge drivers for high reliability.
• Features low EMI operation optimized through controlled dV/dt switching characteristics.
• Includes precise overcurrent protection and temperature feedback via accessible low-side emitters.

Applications

• High-efficiency appliance motor drives
• Fan and pump control systems
• Small home appliances

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the SOP 29x12 surface mount package and slow speed (low EMI) configuration. Ensure compatibility with industrial qualification standards and check for any required external bootstrap components or RC networks for the programmable fault timer.

Selection Notes

Select this component for designs requiring reduced electromagnetic interference in compact motor drive applications. The open emitter configuration allows for direct phase current sensing, while the integrated NTC simplifies thermal management without additional discrete sensors.

Part Context

This part belongs to the CIPOS™ Micro IM241 product group, designed to integrate power and control components to optimize PCB size and system costs. It is available in both fast (low loss) and slow (low EMI) speed variants within the same family.

Replacement Considerations

IM241-M6S1B offers the same package and topology but utilizes fast speed IGBTs for lower conduction losses instead of low EMI optimization.

FAQ

What is the function of the RFE pin?

The RFE pin combines three functions: it acts as an enable input, a fault output that pulls low during under-voltage or overcurrent conditions, and supports a programmable fault clear timer using an external RC network.

How is the internal temperature monitored?

The module contains a built-in NTC thermistor connected to the VTH pin. An external pull-up resistor allows the resulting voltage to be read directly by a microcontroller for temperature monitoring.

What logic levels are supported by the gate driver inputs?

The HIN and LIN pins feature Schmitt-trigger inputs compatible with LSTTL and CMOS logic down to 3.3 V controller outputs, ensuring noise rejection through internal filters.
