Product details
Overview
IMC101TF048XUMA1 from Infineon Technologies is a single-motor, script-enabled, IEC/UL 60730-1 Class B certified iMOTION™ motor control IC for permanent magnet synchronous motors (PMSM). It integrates a Motion Control Engine (MCE), field-oriented control (FOC), flexible space vector PWM, single-leg shunt current sensing, and sensorless or Hall-based position estimation. Used in variable-speed compressor drives requiring certified safety and rapid system deployment.
For engineers reviewing the IMC101TF048XUMA1 datasheet, IMC101TF048XUMA1 pinout, IMC101TF048XUMA1 application, or IMC101TF048XUMA1 equivalent, this page delivers verified technical context, LQFP-48 package mapping, MCE-based FOC implementation details, UART/analog/frequency speed interface options, and validated alternative motor controllers with documented functional trade-offs.
Technical Context
The IMC101TF048XUMA1 implements a hardware-accelerated Motion Control Engine (MCE) that executes real-time FOC without host CPU intervention, using a dedicated 96 MHz oscillator and 12-bit ADC with programmable gain for current sensing. Its integrated script engine runs application-level logic in parallel with the MCE, enabling custom fault responses and user interface control without modifying core motor algorithms.
It supports three-phase gate drive via six independent PWM outputs (PWMUH/PWMUL, PWMVH/PWMVL, PWMWH/PWMWL), configurable for MOSFET or IGBT power stages, with built-in analog comparators for over-current protection and an on-die temperature sensor for thermal monitoring. Safety functions comply with IEC/UL 60730-1 Class B requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
LQFP-48 package with exposed thermal pad (PG-LQFP-48-10); 0.5 mm pitch, 7 mm × 7 mm body, JEDEC standard footprint compatible with automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (pins 21, 28, 38) | Power supply input | 3.3–5.0 V main supply; three pins ensure low-impedance routing for digital and analog domains. |

| PWMVH (pin 25) | Phase V high-side gate drive | Independent high-side output for second phase; enables full 3-phase 6-step or sinusoidal excitation. |
| PWMVL (pin 24) | Phase V low-side gate drive | Paired with PWMVH; configured in hardware to prevent cross-conduction during switching transitions. |
| AIN0–AIN5 (pins 1–6) | Analog inputs | Configurable for current sense (shunt), DC bus voltage, temperature, or Hall sensor signals; 12-bit ADC multiplexed across six channels. |
| UART_TX/RX (pins 45, 46) | Serial communication interface | Full-duplex UART at up to 115.2 kbps; used for parameter upload, runtime diagnostics, and firmware updates. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Motion Control Engine (MCE) | Hardware-accelerated FOC execution offloads all motor control math from host MCU-reduces BOM cost and software validation effort. |
| Script Engine | Runs C-like application code alongside MCE; enables custom LED status logic, error logging, or multi-speed profiles without altering motor algorithm. |
| Sensorless + Hall Support | Single firmware image supports both sensorless startup and Hall-based steady-state operation-eliminates need for dual hardware variants. |
| Class B Safety Functions | Includes clock failure detection, supply voltage monitoring, watchdog timeout, and fault response sequencing-meets appliance safety certification out-of-box. |
| Flexible Speed Inputs | Accepts analog voltage, frequency, or PWM duty cycle as speed command-simplifies integration with potentiometers, microcontrollers, or PLCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMSM motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IMC102TF048XUMA1 | Includes integrated boost/totem-pole PFC controller; adds two high-voltage gate drivers and PFC-specific ADC channels. | Required when AC input stage must meet EN 61000-3-2 harmonic limits; not needed for DC-fed or pre-regulated systems. | Select IMC102T only if PFC is mandatory; otherwise IMC101T reduces component count and layout complexity. |
| IMC101TQ048XUMA1 | Same MCE and script engine, but in VQFN-48 (PG-VQFN-48-73) with exposed thermal pad; 0.4 mm pitch, smaller footprint. | Better suited for space-constrained designs like portable appliances; requires tighter stencil design and reflow profile control. | Choose QFN for size-critical applications; select LQFP for easier prototyping, thermal management, and legacy PCB compatibility. |
Compared with IMC102TF048XUMA1, the IMC101TF048XUMA1 omits PFC circuitry-reducing BoM cost and simplifying layout-while retaining identical motor control performance. Against IMC101TQ048XUMA1, it trades compactness for manufacturability and thermal margin in industrial-grade assemblies.

FAQ
Does IMC101TF048XUMA1 require an external microcontroller to operate?
No. The IMC101TF048XUMA1 contains a self-contained Motion Control Engine (MCE) that executes field-oriented control autonomously. It accepts speed commands via UART, analog voltage, frequency, or duty cycle inputs and drives external gate drivers directly-no host MCU is needed for basic operation.
What current sensing topologies does IMC101TF048XUMA1 support?
It supports single-shunt and leg-shunt configurations using its integrated 12-bit ADC with programmable gain. The MCE automatically reconstructs all three phase currents from either topology, enabling accurate torque control without external op-amps or isolated amplifiers.
Can IMC101TF048XUMA1 drive both MOSFETs and IGBTs?
Yes. Its six PWM outputs (three high-side, three low-side) are CMOS-compatible and designed to interface with standard gate driver ICs for both MOSFET and IGBT power stages. Output timing parameters-including dead-time generation-are configurable via the MCE GUI or script engine.
Is the script engine capability enabled on IMC101TF048XUMA1?
Yes. Unlike the IMC099T variant, the IMC101T series includes full script engine functionality. Users can implement custom logic-for example, LED status sequencing, multi-stage startup, or fault logging-without modifying the underlying MCE motor control algorithm.
