Infineon Technologies IM818MCCXKMA1

Overview

IM818MCCXKMA1 from Infineon Technologies is a fully isolated three-phase intelligent power module (IPM) integrating 1200 V TRENCHSTOP™ IGBT4s, emitter-controlled diodes, and a rugged 6-channel SOI gate driver. It delivers ±16 A continuous output current at TC = 25°C, supports 900 V DC bus voltage, and includes integrated NTC thermistor, over-current shutdown, and under-voltage lockout for industrial motor drives.

For engineers reviewing the IM818MCCXKMA1 datasheet, IM818MCCXKMA1 pinout, IM818MCCXKMA1 application, or IM818MCCXKMA1 equivalent, key selection criteria include high-side floating supply tolerance (−11 V VS potential), programmable fault-clear timing via RFE pin, open-emitter low-side emitter pins (NU/NV/NW) for phase current sensing, and thermal resistance of 1.85 K/W per high-side IGBT.

Technical Context

The IM818MCCXKMA1 implements a six-pack inverter topology with independent high- and low-side gate drivers per phase, using SOI-based isolation to sustain 2500 V RMS isolation and −50 V transient VS robustness. Its bootstrap-based high-side supply supports up to 1200 V blocking capability with VBSUV− = 10.2 V under-voltage detection.

Control logic features Schmitt-trigger inputs compatible with 3.3 V/5 V microcontrollers, integrated shoot-through prevention with 360 ns minimum dead time, and noise-filtered ITRIP input (t_ITRIP = 500 ns) referenced to VSS. Fault handling is centralized through the bidirectional RFE pin, enabling latch-off shutdown, external fault clear timing (e.g., 1 ms with 1 MΩ + 2 nF), and enable/disable control.

FAQ

What is the maximum allowable DC bus voltage for IM818MCCXKMA1?

The absolute maximum DC link supply voltage between P and N is 900 V under normal operation, with a surge rating of 1000 V for ≤10 ms. Exceeding 900 V continuously risks premature IGBT degradation and violates JEDEC qualification limits. The module's 1200 V blocking rating provides design margin but does not permit sustained operation above 900 V.

How is phase current measured using NU, NV, and NW pins?

NU, NV, and NW are low-side emitter terminals that expose each IGBT's emitter node separately. A shunt resistor placed between each pin and VSS enables direct Kelvin-sensing of phase current. Layout must minimize trace inductance - recommended routing uses short, wide copper pours directly to VSS ground plane to avoid voltage spikes corrupting measurements.

Can the RFE pin be used solely as a fault output without external RC network?

Yes - RFE operates as an open-drain fault indicator by default: it pulls low during UVLO or ITRIP events and floats high otherwise. No external RC is needed for basic fault signaling. The RC network is optional and only required when programmable auto-clear timing (e.g., 1 ms recovery delay) is desired; omitting it leaves fault latched until MCU actively clears via RFE low pulse.

What thermal derating applies above TC = 25°C?

At TC = 80°C, continuous current rating drops to ±10 A per phase due to thermal resistance limitations. Derating follows linear interpolation: from ±16 A at 25°C to ±10 A at 80°C. Junction temperature must remain ≤150°C; this requires heatsink thermal resistance ≤1.1 K/W when dissipating 67.5 W per IGBT at full load.
