Infineon Unveils iMOTION IMM100 Series: Compact Motor Controllers that Shrink PCBs and Accelerate Development

Infineon Technologies has introduced the iMOTION IMM100 series—smart IPM motor controllers that combine full hardware and software integration for BLDC drives up to 80 W, all without a heatsink. The new IC merges the motor controller and a 3‑phase inverter stage into a single, remarkably compact 12 × 12 mm 2‑PQFN package. This tight integration cuts both BOM count and PCB footprint, driving down overall system cost. The tiny footprint makes the IMM100 ideal for space‑constrained appliances such as hair dryers, kitchen hoods, ceiling and air‑conditioner fans, and for pumps in dishwashers and washing machines. The platform also serves low‑power fridge compressors, heating pumps, and industrial pumps.

The series offers two carefully engineered variants to meet the distinct needs of design engineers. The T‑variant embeds the sophisticated Field‑Oriented Control (FOC) algorithm within Infineon’s Motion Control Engine 2.0 (MCE 2.0). It harnesses intuitive software tools for system configuration and tuning, and can be extended with iMOTION scripting and optional Power‑Factor Correction (PFC) control. The A‑variant empowers engineers to develop proprietary motor‑control firmware on a fully programmable ARM Cortex‑M0 MCU, while still benefiting from the complete hardware integration. The industry‑standard ARM IDE ecosystem supports the entire software lifecycle—from coding and compiling to debugging—streamlining development.

Both variants dramatically shorten the hardware R&D cycle thanks to their high degree of integration. The T‑variant, in particular, reduces R&D cost and accelerates time‑to‑market with production‑ready MCE 2.0 software. The IMM100 series comes in three MOSFET‑based power stages—500 V / 6 Ω, 600 V / 1.4 Ω, and 600 V / 0.95 Ω—to match performance and cost targets. Devices support flexible sensing, including single‑shunt, leg‑shunt (sensorless), and Hall‑sensor topologies, and feature robust protection such as under‑/over‑voltage, over‑current, rotor‑lock, and shoot‑through safeguards.
