New iMOTION SmartDriver family with three-phase gate driver

23 February 2021

The new IMD110 SmartDriver series from Infineon Technologies AG is a smart motor controller family combining the iMOTION Motion Control Engine (MCE) with a three-phase gate driver in a compact package. The integrated gate driver is based on the company’s unique silicon-on-insulator (SOI) technology and can drive a wide variety of metal-oxide semiconductor field-effect transistors (MOSFETs) and insulated-gate bipolar transistors in variable speed drives.

The family uses the latest MCE 2.0, which provides a ready-to-use motor and, optionally, power factor correction (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.Source: Infineon Technologies AGSource: Infineon Technologies AG

Infineon’s field-proven MCE 2.0 implements highly efficient field-oriented control 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. 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 and 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, a modular and flexible development platform providing a wide range of control and power board options for motor drive applications up to 1 kW.
