IM241M6T2BAKMA1

Overview

The IM241M6T2BAKMA1 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 topology with a rated collector current of 4 A and a maximum DC link voltage of 400 V. The device includes built-in NTC thermistor monitoring, overcurrent shutdown via the ITRIP pin, and programmable fault clearing through the RFE pin. Designed for industrial applications, it operates within a junction temperature range of -40°C to 150°C and offers isolation voltages up to 2000 VRMS.

Feature Summary

• Integrates reverse conducting IGBT technology with rugged half-bridge drivers for optimized loss and EMI trade-offs.
• Provides precise overcurrent protection and temperature feedback via accessible low-side emitter pins and an internal NTC.
• Features fully isolated DIP and SOP modules with lead-free terminal plating compliant with RoHS standards.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and speed variant. Ensure that any additional characters in the part number do not indicate non-standard packaging or regional specifications. Cross-reference the manufacturer's latest datasheet to validate active status and compliance requirements before finalizing procurement orders.

Selection Notes

Select this component for designs requiring integrated protection features such as shoot-through prevention and undervoltage lockout. Consider the fast speed version for low-loss applications or slow speed variants for reduced EMI. Ensure the external dead time exceeds the internal minimum of 300 ns and verify that the logic inputs are compatible with 3.3 V or 5.0 V controller outputs.

Part Context

This module belongs to the CIPOS Micro IM241 product group, which integrates various power and control components to optimize PCB size and system costs. The series is designed specifically for high-efficiency motor drives in appliances, offering both surface mount and through-hole configurations to suit different manufacturing needs.

Replacement Considerations

Compatible substitutes within the same family include IM241-M6T2B2AKMA1 and IM241-M6S1B. Verify that alternative part numbers match the required DIP or SOP package and confirm that the speed variant (fast or slow) aligns with the application's loss or EMI constraints.

FAQ

How does the RFE pin function?

The RFE pin combines three functions: RC-network based programmable fault clear timer, fault output, and enable input. It can be pulled low by a microcontroller to disable the IPM or reports faults by pulling low during under-voltage or overcurrent conditions.

What is the purpose of the low-side emitter pins?

The low-side emitter pins (NU, NV, NW) are accessible for phase current monitoring. They allow for external current sensing using shunt resistors, facilitating precise control and protection of the motor phases.

What protection features are included in the IPM?

The IPM includes overcurrent shutdown, shoot-through prevention with a typical 300 ns internal deadtime, undervoltage lockout for both control and high-side supplies, and temperature monitoring via the built-in NTC thermistor.
