Product details
Overview
IM818LCCXKMA1 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 motor phase currents up to ±20 A at TC = 25°C, supports 900 V DC bus operation, and includes integrated NTC thermistor, overcurrent shutdown, and anti-cross-conduction logic for HVAC fan drives and low-power servo inverters.
For engineers reviewing the IM818LCCXKMA1 datasheet, IM818LCCXKMA1 pinout, IM818LCCXKMA1 application, or IM818LCCXKMA1 equivalent, key selection considerations include its 1200 V blocking capability, open-emitter low-side emitter pins (NU/NV/NW) for phase current sensing, programmable fault-clear timing via RFE pin, and -50 V transient VS robustness against negative voltage spikes.
Technical Context
The IM818LCCXKMA1 implements a six-pack inverter topology with independent high- and low-side gate drivers per phase, using SOI technology for inherent electrical isolation and immunity to dV/dt-induced false triggering. Its bootstrap-based high-side supply (VB/VS pairs) enables floating operation up to 1200 V offset, while internal shoot-through prevention enforces minimum 360 ns dead time between complementary HIN/LIN inputs.
Control logic operates from a single 12.2–20 V VDD supply referenced to VSS, with under-voltage lockout (UVLO) thresholds at 12.2 V (turn-on) and 11.2 V (shutdown). Overcurrent detection triggers within 1 µs propagation delay when ITRIP exceeds 0.5 V, latching all outputs until cleared via RFE pin or power cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Blocking Voltage | 1200 V - Enables use in 690 V AC industrial systems with 2× safety margin and surge tolerance up to 1000 V DC. |
| Continuous Current | ±20 A @ TC = 25°C - Supports 1–2 kW motor drives without forced cooling in compact enclosures. |
| DC Bus Voltage | 900 V max - Matches standard 3-phase rectified input for HVAC and pump inverters. |
| Thermal Resistance | 0.80 K/W (IGBT), 1.30 K/W (diode) - Enables direct heatsink mounting with predictable junction temperature rise. |
| Fault Response Time | 1 µs propagation + 1.1 ms clear time - Ensures fast short-circuit protection while allowing configurable recovery window. |
| Input Logic Compatibility | LSTTL/CMOS down to 3.3 V - Interfaces directly with mainstream microcontrollers without level-shifting. |
Pinout & Package
IM818LCCXKMA1 uses a DIP-24 (36 × 23 mm) fully isolated molded package with creepage/clearance optimized for industrial motor drive safety standards. The bottom-view layout features 24 terminals: 6 high-side supply pins (VB/VS per phase), 6 control inputs (HIN/LIN), 3 motor outputs (U/V/W), 3 low-side emitters (NU/NV/NW), and dedicated fault/thermistor/control pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS(U), VS(V), VS(W) | High-side floating supply offset reference | Enables robust -50 V transient tolerance relative to VSS, critical for EMI-heavy motor drive environments. |
| VB(U), VB(V), VB(W) | High-side floating supply voltage input | Feeds SOI gate driver stages; internally bootstrapped, eliminating external high-side bias supplies. |
| HIN(U–W), LIN(U–W) | Phase gate drive enable inputs | Positive-logic, Schmitt-triggered with 5 kΩ internal pull-down and 1 µs minimum pulse width requirement. |
| NU, NV, NW | Low-side emitter access points | Enable shunt-based phase current monitoring without breaking the power path; require short trace routing to VSS. |
| RFE | Multi-function pin (fault-out / enable / RC-clear timer) | Combines fault signaling, MCU-driven disable, and externally programmable recovery delay (e.g., 1 MΩ + 2 nF = 1.1 ms). |
| VTH | NTC thermistor connection | Provides direct access to integrated temperature sensor referenced to VSS; requires external 5 V pull-up for MCU ADC interface. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Bootstrap Functionality | Eliminates need for external high-side gate drive bias supplies, reducing BOM count and PCB area in 3-phase inverter designs. |
| Programmable Fault-Clear Timing | RC network on RFE pin allows system-level tuning of recovery delay after overcurrent or UV fault, preventing nuisance tripping. |
| Open-Emitter Low-Side Outputs | NU/NV/NW pins provide Kelvin connections for accurate shunt-based phase current measurement without ground loop interference. |
| Anti-Cross-Conduction Logic | Hardware-enforced dead time (360 ns typ.) and input arbitration prevent simultaneous HO/LO activation on same leg, ensuring safe switching. |
| 1200 V SOI Gate Driver | SOI process delivers intrinsic isolation and immunity to fast transients, enabling reliable operation in noisy industrial EMI environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FSB50550 | 600 V rating, lower current (15 A), no integrated thermistor, TO-263-15 package | Suitable only for 400 V AC systems; lacks NTC and open-emitter pins for advanced current sensing | Select when cost sensitivity outweighs thermal monitoring and 900 V bus requirements. |
| IRAMS10UP60B | 600 V rating, 10 A continuous, built-in current sense resistor, DIP-23 package | Designed for lower-power appliances; fixed current sense gain limits dynamic range vs. NU/NV/NW flexibility | Choose for simple, low-cost fan/pump drives where precision phase current resolution is not required. |
Compared with FSB50550 and IRAMS10UP60B, IM818LCCXKMA1 provides higher voltage headroom (1200 V), full open-emitter access for calibrated shunt sensing, and integrated NTC-making it uniquely suited for industrial HVAC, servo, and active filter designs demanding reliability, thermal awareness, and 900 V DC bus compatibility.

FAQ
What is the maximum allowable DC link voltage for IM818LCCXKMA1?
The absolute maximum DC link 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 failure due to increased conduction losses and thermal stress beyond the specified 0.80 K/W RthJC limit.
How is phase current measured using the NU, NV, and NW pins?
NU, NV, and NW are Kelvin-connected low-side emitter terminals that allow insertion of precision shunt resistors between each pin and VSS. This configuration avoids power-path inductance errors, enabling accurate real-time current sampling synchronized with PWM switching cycles for field-oriented control.
Can the RFE pin be used solely as a fault output without external RC timing?
Yes-RFE functions as an open-drain fault indicator by default. When pulled high via external resistor, it goes low during UV or overcurrent faults. No RC network is required for basic fault signaling; the RC is only needed if programmable auto-clear timing is desired after fault removal.
Does IM818LCCXKMA1 require external bootstrap diodes or capacitors?
No-integrated bootstrap circuitry eliminates external diodes. However, external bootstrap capacitors (typically 0.22–1 µF ceramic) must be placed close to each VB/VS pair to maintain stable high-side supply during PWM operation and prevent gate drive collapse under high-duty-cycle conditions.
