Infineon Technologies AG has introduced smart IPM motor controllers featuring full hardware and software integration needed for BLDC motor drives of up to 80W without heatsink. The new iMOTION IMM100 series combines the motor controller IC and a three-phase inverter stage in a single, highly compact 12×12 mm2 PQFN package. This combination enables BOM count and PCB size reduction, thus lowering system cost. The smallest footprint of the motor drive IC makes it a perfect fit for space restrained home appliances like hair dryers, kitchen hoods, ceiling, and air conditioner fans as well as pumps for dishwasher and washing machines. Additional applications include low-power fridge compressors, heating pumps, and industrial pumps. The series offers two optimized variants to serve the needs of design engineers.
The series of motor control ICs features three different MOSFET-based power stages: 500 V/6 Ω, 600 V/1.4 Ω, and 600 V/0.95 Ω to match designers’ performance and cost targets. These devices also offer flexible sensing options by supporting single-shunt or leg-shunt topologies (sensorless option), as well as supporting hall sensors. Additionally, the IMM100 integrates multiple protection features, such as under-/over-voltage protection, over-current protection, rotor lock, and shoot-through protection.
