Infineon’s iMOTION IMM100 Smart IPM Motor Controllers Reduce Ease Motion Design

February 19, 2019 Alix Paultre

Infineon Technologies’ smart IPM motor controllers for BLDC motor drives of up to 80W integrate the motor controller IC and a 3-phase inverter stage in a 12 x 12 mm 2 PQFN package. Suitable for space-restrained products, the IMM100 series offers two optimized variants: the T-variant with an FOC algorithm and software tools for system configuration and tuning with iMOTION scripting and, optionally, PFC control. The IMM100 A-variant has an integrated ARM Cortex-M0 MCU with IDE tools to support the software design process, compiling, and debugging.

MOTION IMM100 motor control ICs offer three MOSFET-based power stages: 500 V / 6 Ω, 600 V / 1.4 Ω and 600 V / 0.95 Ω. These devices support single-shunt or leg-shunt topologies (sensorless option), as well as Hall sensors. Additionally, the IMM100 integrate multiple protection features like under-/over-voltage protection, over-current protection, rotor lock, and shoot-through protection.
