Infineon Technologies IM241S6S1BAUMA1

Overview

IM241S6S1BAUMA1 from Infineon Technologies is a CIPOS™ Micro Intelligent Power Module (IPM) integrating six reverse-conducting RCD2 IGBTs, three half-bridge gate drivers, bootstrap circuitry, fault reporting, and an NTC thermistor in a single SOP-29x12 surface-mount package. It delivers 600 V blocking voltage, 3.3 V/5.0 V logic compatibility, and open-emitter low-side emitter pins (NU, NV, NW) for phase current sensing - designed specifically for high-efficiency, low-EMI motor drives in compact home appliance fans and pumps.

For engineers reviewing the IM241S6S1BAUMA1 datasheet, IM241S6S1BAUMA1 pinout, IM241S6S1BAUMA1 application, or IM241S6S1BAUMA1 equivalent, key selection considerations include its fast-speed "B" variant optimized for low conduction loss, integrated shoot-through protection with 300 ns deadtime, programmable fault-clear timing via RFE pin, and isolated 2000 VRMS rating for industrial-grade reliability.

Technical Context

This IPM implements a three-phase inverter topology with independent high-side (HIN/U/V/W) and low-side (LIN/U/V/W) gate inputs, each featuring Schmitt-trigger logic, internal pull-down resistors (~800 kΩ), and input noise filtering (t_FIL,IN ≥ 1 µs). The RFE pin integrates enable, fault reporting, and RC-programmable auto-restart functionality, while ITRIP provides overcurrent shutdown with 500 ns input filtering.

Each high-side driver uses floating bootstrap supplies (VB/U/V/W to VS/U/V/W), with undervoltage lockout at 10.9 V (falling) / 11.1 V (rising); low-side control supplies (VDD1/VDD2/VDD3) share common VSS reference. The built-in NTC connects to VTH pin for temperature monitoring, and all low-side emitters (NU/NV/NW) are externally accessible for shunt-based current measurement.

FAQ

What is the purpose of the RFE pin on IM241S6S1BAUMA1?

The RFE pin serves three functions: it acts as an enable input (active-low), a fault-reporting output (open-drain, pulled low during UVLO or ITRIP events), and an interface for an external RC network that sets the automatic fault-clear timeout. When configured with R_RFE = 1.2 MΩ and C_RFE = 1 nF, it provides ~1.7 ms delay before automatic restart after fault clearance - eliminating need for MCU intervention in transient overcurrent conditions.

Can IM241S6S1BAUMA1 be used with 3.3 V microcontrollers without level shifters?

Yes. All digital inputs (HINx, LINx, RFE, ITRIP) are 3.3 V and 5.0 V logic compatible, featuring Schmitt-trigger thresholds and internal pull-down resistors (~800 kΩ). No external level shifting is required - direct connection to 3.3 V MCU GPIOs is supported, and input noise filtering ensures robust operation even in electrically noisy motor drive environments.

How is temperature monitoring implemented on this IPM?

Temperature monitoring uses an integrated NTC thermistor connected to the VTH pin, which is referenced to VSS. An external pull-up resistor (e.g., 10 kΩ to +5 V or VDD) converts thermistor resistance into a measurable analog voltage. This voltage scales linearly with die temperature and can be read directly by an MCU's ADC without signal conditioning - enabling real-time thermal derating or shutdown decisions.

What does "S6S1" and "B" indicate in the part number IM241S6S1BAUMA1?

"S6S1" denotes the SOP-29x12 package variant with "S1" indicating the slow-speed version - but IM241S6S1BAUMA1 is an exception: the "B" suffix overrides that, specifying the *fast-speed* variant optimized for low conduction loss (not low EMI). This combination reflects Infineon's packaging and speed binning scheme: "S" = SOP, "6" = 600 V, "S1" = SOP base code, "B" = fast speed, "AUMA1" = tape-and-reel packaging and revision.
