80W IPM Motor Controllers with 3-Phase Inverter and Software Integration
Infineon Technologies AG introduced smart IPM motor controllers featuring full hardware and software integration needed for BLDC motor drives of up to 80W without a heatsink. The new iMOTION™ IMM100 series combines the motor controller IC and a 3-phase inverter stage in a single 12mm x 12mm2 PQFN package. This combination enables a BOM count and PCB size reduction, thus lowering system cost.
The smallest footprint of the motor drive IC makes it a suitable fit for space restrained home appliances such as hair dryers, kitchen hoods, ceiling, and air conditioner fans as well as pumps for washing machines and dishwashers. Additional applications include low-power fridge compressors, heating pumps, and industrial pumps.
The IMM100 series offers two optimized variants to serve the needs of design engineers. The T-variant uses a highly sophisticated FOC algorithm integrated into the iMOTION MCE 2.0 (Motion Control Engine 2.0). This variant takes advantage of software tools for system configuration and tuning. System-level functions can be added with iMOTION scripting and optionally, with PFC control.
Another option with the IMM100 A-variant, lets engineers implement the proprietary motor control software using the integrated ARM® Cortex®-M0 MCU. This option gives designs the benefits of complete hardware integration. In this case, the industry-standard ARM® MCU IDE tools support the software design process, compiling, and debugging. According to Infineon, both variants reduce R&D cycle time for the hardware design due to their high levels of integration.
Moreover, the T-variant significantly reduces the R&D cost and speeds up time-to-market thanks to production-ready MCE 2.0 software integration.
The iMOTION IMM100 series of motor control ICs features three different MOSFET-based power stages: 500V/6Ω, 600V/1.4Ω, and 600V/0.95Ω to best match designers' performance and cost targets. These devices also provide flexible sensing alternatives by supporting single-shunt or leg-shunt topologies (sensorless option), as well as supporting Hall sensors.
Additionally, the IMM100 integrate multiple protection features, including under- and over-voltage protection, over-current protection, rotor-lock, and shoot-through protection.
Samples and evaluation boards for the iMOTION IMM100 will be available from April 2019; the release to production is planned for May 2019.
Infineon invites attendees of Embedded World 2019 Exhibition & Conference in Nuremberg, Germany; February 26 - 28, 2019 to visit the company's booth 231 in hall 3A. Highlights of their showcase include solutions for smart, safe vehicles that drive automatically; connected, secure factories; smart homes, and consumer devices; as well as highly efficient and sophisticated drones.
