IMD111T6F040XUMA1

Overview

The IMD111T6F040XUMA1 is a three-phase motor control integrated circuit from the iMOTION family, designed for sensorless field-oriented control (FOC) of brushless DC motors. It integrates an Arm Cortex-M0 core with high-accuracy analog front-end capabilities and state-machine-based digital loop control. The device supports PWM and PFM control loops, featuring programmable configurations and integrated voltage and current sensing. It operates within a supply voltage range of 3 V to 5.5 V and functions reliably across temperatures from -40°C to +125°C. Packaged in a 40-LQFP format, it offers GPIOs, I-ADC, and V-ADC interfaces for system integration.

• Integrates an Arm Cortex-M0 core with state-machine based fast control loop for precise motor management
• Supports sensorless field-oriented control (FOC) with high-accuracy analog frontend performance
• Features programmable configurations and integrated voltage and current sensing capabilities
• Compatible with isolated and non-isolated topologies for versatile application deployment

Applications

• Refrigerator compressor drives
• Home appliance motor control systems
• Industrial fan and pump applications
• Brushless DC motor drives

Procurement Notes

Verify the specific ordering suffix XUMA1 to confirm tape-and-reel packaging configuration. Ensure compatibility with the target motor type, as this component is optimized for BLDC applications. Check humidity sensitivity requirements during storage and handling. Confirm that the 40-LQFP package dimensions align with the PCB layout constraints. Validate that the operating temperature range meets the environmental specifications of the final assembly.

Selection Notes

Select this component when sensorless FOC is required for three-phase BLDC motors without external sensors. The integrated analog frontend reduces bill-of-materials complexity by eliminating separate sensing circuits. Consider the 40-LQFP package for adequate thermal dissipation and pin count. Evaluate the need for PMBus or other communication interfaces if remote monitoring is necessary. Ensure the input voltage range matches the system power supply architecture.

Part Context

This part belongs to the iMOTION family of motor control ICs from Infineon Technologies. The series is engineered for mid-power applications requiring high efficiency and compact design. It complements discrete gate drivers and power stages, such as CoolMOS or IGBTs, to form complete motor drive solutions. The family emphasizes firmware-based differentiation and ease of configuration for various industrial and consumer markets.

Replacement Considerations

Check for variants within the IMD111T series with different package options or output configurations. Verify functional equivalence with older generation iMOTION devices if migrating existing designs. Ensure substitute parts support the same sensorless FOC algorithms and analog frontend accuracy levels.
