Product details
Overview
IMC101TQ048XUMA1 from Infineon Technologies is a single-motor, script-enabled iMOTION™ turnkey motor control IC for permanent magnet synchronous motors (PMSM), featuring integrated Field-Oriented Control (FOC), 96 MHz oscillator, 12-bit ADC with multiplexer, space vector PWM generation, and IEC/UL 60730-1 Class B safety certification - deployed in variable-speed home appliance compressors.
For engineers reviewing the IMC101TQ048XUMA1 datasheet, IMC101TQ048XUMA1 pinout, IMC101TQ048XUMA1 application, or IMC101TQ048XUMA1 equivalent, key selection criteria include motor control architecture (MCE + script engine), shunt-based current sensing capability (single/leg), Hall/sensorless position interface options, and QFN-48 thermal performance for compact inverter designs.
Technical Context
The IMC101TQ048XUMA1 implements a dual-layer motion control architecture: the Motion Control Engine (MCE) handles real-time FOC execution and fault management, while the independent script engine enables application-level logic (e.g., speed ramping, state transitions) without modifying core motor algorithms. It supports both analog Hall and digital Hall inputs, plus sensorless estimation via back-EMF observation.
Its 3-phase gate driver outputs (6x PWM: UL/UH/VL/VH/WL/WH) drive external MOSFETs or IGBTs, with integrated analog comparators for cycle-by-cycle over-current protection and a built-in temperature sensor for thermal derating. The device operates from 3.3 V to 5.0 V supply and includes internal voltage supervision and watchdog timer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Motor Control Core | Motion Control Engine (MCE) + independent script engine for application customization without altering FOC firmware |
| PWM Frequency | Up to 20 kHz space vector PWM - enables low-acoustic-noise sinusoidal drive for PMSM fans and compressors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMSM motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IMC102T-F048 | LQFP-48 package with integrated boost/totem-pole PFC controller - adds 2x additional high-voltage gate drivers and PFC-specific ADC channels | Required when system-level power factor correction is mandated (e.g., EU ErP Lot 11 compliance) | Select IMC102T-F048 only if PFC functionality is needed; IMC101TQ048XUMA1 offers lower cost and smaller footprint for standalone motor control |
| IMC101T-F048 | LQFP-48 package (10 mm × 10 mm) vs. QFN-48 (7 mm × 7 mm); identical electrical specs but higher θJA (48 °C/W) and no exposed thermal pad | Suitable for less thermally constrained layouts where PCB routing simplicity outweighs thermal density needs | Choose IMC101T-F048 for ease of manual rework or legacy LQFP-compatible tooling; IMC101TQ048XUMA1 preferred for space-constrained inverter modules |
Compared with IMC102T-F048 and IMC101T-F048, IMC101TQ048XUMA1 delivers optimal thermal performance and minimal board area for cost-sensitive, single-motor PMSM drives - making it the default choice when PFC is handled externally or not required.

FAQ
What motor types does IMC101TQ048XUMA1 support?
IMC101TQ048XUMA1 is designed exclusively for permanent magnet synchronous motors (PMSM). It supports both sensorless operation (back-EMF observer) and Hall sensor-based commutation, but does not support induction motors (IM), brushed DC, or stepper motors. Its FOC engine is optimized for sinusoidal current waveforms typical of PMSM loads.
Does IMC101TQ048XUMA1 require external gate drivers?
No. IMC101TQ048XUMA1 integrates six high-current gate drivers (three high-side, three low-side) capable of directly driving standard 600 V MOSFETs or IGBTs with peak output current ≥1.5 A. External level-shifters or buffer stages are unnecessary unless using >1200 V devices or ultra-high dV/dt isolation requirements.
Can the script engine modify motor control parameters in real time?
Yes. The script engine runs independently of the Motion Control Engine and can adjust MCE parameters such as target speed, torque limit, acceleration ramp rate, and fault response behavior via shared RAM registers - all without interrupting FOC loop execution or requiring firmware reload.
Is IMC101TQ048XUMA1 qualified for automotive use?
No. IMC101TQ048XUMA1 is qualified for industrial applications per JEDEC47/20/22 stress tests and carries IEC/UL 60730-1 Class B certification, but it is not AEC-Q100 qualified and lacks automotive temperature range (−40 °C to +125 °C) or humidity testing. It is intended for home appliances and industrial equipment.
