Infineon Technologies AG’s IMD110 SmartDriver series of smart motor controllers combines the iMOTION Motion Control Engine (MCE) with a three-phase gate driver in a compact package. Based on the company’s silicon-on-insulator (SOI) technology, the device can drive a wide variety of MOSFETs and IGBTs in variable speed drives.

The SmartDriver family uses the latest MCE 2.0, which provides a ready-to-use motor and, optionally, PFC control. Applying the MCE for controlling the motor, customers can focus on their system design. Key target applications are motors in major home appliances as well as fans and pumps.

Infineon’s field-proven MCE 2.0 implements highly efficient field-oriented control (FOC) in sensorless or hall-based motor inverters. The wide operating voltage of the SOI gate driver addresses battery and mains powered motors and delivers market-leading robustness and reliability. An integrated voltage regulator enables several supply schemes and helps to achieve a reduced bill of material (BOM). IMD110 devices are pre-certified for applications requiring functional safety according to UL/IEC 60730 (Class B).

IMD110 variants are offered for motor drives with and without PFC control. Devices in LQFP-40 packages are in mass production, they are pin-compatible with LQFP-48 packages. Rapid prototyping of a drive inverter is enabled via two new control boards for the iMOTION Modular Application Design Kit (MADK). MADK is a modular and flexible development platform providing a wide range of control and power board options for motor drive applications up to 1 kW.
