Infineon Technologies IM828XCCXKMA1

Overview

IM828XCCXKMA1 from Infineon Technologies is a fully isolated three-phase CIPOS™ Maxi intelligent power module integrating six 1200V CoolSiC™ MOSFETs and an optimized 6-channel SOI gate driver. It serves as a high-performance inverter for industrial motor drives and active power factor correction, delivering ±35 A continuous phase current at TC = 25°C, 900 V DC-link voltage capability, and integrated NTC thermistor for thermal monitoring.

For engineers reviewing the IM828XCCXKMA1 datasheet, IM828XCCXKMA1 pinout, IM828XCCXKMA1 application, or IM828XCCXKMA1 equivalent, key selection considerations include its 1200V SiC MOSFET blocking rating, -11 V allowable negative VS potential under VBS = 15 V, programmable fault-clear timing via RFE pin, open-source low-side source pins (NU/NV/NW) for phase current sensing, and built-in anti-cross-conduction logic with 300 ns minimum deadtime.

Technical Context

The IM828XCCXKMA1 implements a three-phase inverter topology with independent high- and low-side gate drivers per phase, using SOI-based isolation to sustain ±1200 V offset voltage between floating high-side supplies (VB/VS) and control ground (VSS). Its bootstrap-supplied high-side drivers support synchronous rectification by enabling MOSFET turn-on during body-diode conduction.

Protection architecture includes overcurrent shutdown triggered at 0.5 V ITRIP threshold (500 ns noise filter), under-voltage lockout on VDD (12.2 V turn-on, 11.2 V turn-off) and VBS (11.2 V/10.2 V), and simultaneous six-switch shutdown upon fault detection. Fault clear timing is externally programmable via RC network on RFE pin.

FAQ

What is the maximum DC-link voltage supported by IM828XCCXKMA1?

The IM828XCCXKMA1 supports a maximum continuous DC-link voltage of 900 V between P and N terminals, with a 1000 V surge rating. This is validated per datasheet Table 3.2 and aligns with industrial 690 VAC three-phase input rectified to ~950 V peak, allowing safe operation with margin. Exceeding 900 V continuous violates absolute maximum ratings and risks catastrophic failure.

Can the NTC thermistor be read directly by a microcontroller ADC?

Yes-the VTH pin provides direct access to the integrated NTC thermistor referenced to VSS. An external 5 V pull-up resistor creates a voltage divider with the NTC, producing a temperature-dependent analog voltage (e.g., ~2.5 V at 25°C) compatible with standard 0–3.3 V or 0–5 V microcontroller ADC inputs without signal conditioning.

How does the RFE pin function as both fault output and enable input?

RFE operates bidirectionally: during normal operation, it outputs an open-drain active-low fault signal (e.g., under-voltage or overcurrent); during startup or fault recovery, an external MCU can pull RFE low to disable all gate drivers. The internal circuit includes a Schmitt-trigger and bi-directional logic that separates these modes based on voltage thresholds and timing-no external components needed beyond the RC network for fault-clear timing.

Are the NU, NV, NW pins truly Kelvin connections for current sensing?

Yes-NU, NV, and NW are dedicated low-side source terminals physically separated from the main power return path. Each connects directly to the source of its respective low-side MOSFET, enabling true Kelvin sensing with minimal parasitic inductance. Layout guidelines in the datasheet require short, direct traces to VSS to preserve accuracy, confirming their role as precision current-sense nodes-not shared return paths.
