Product details
Overview
IMC101TT038XUMA1 from Infineon Technologies is a single-motor, Class B-certified iMOTION™ turnkey motor control IC implementing Field-Oriented Control (FOC) for PMSM drives with integrated Motion Control Engine (MCE), script engine, 3-phase gate driver (6x PWM outputs), and analog current sensing via single or leg shunt - deployed in home appliance compressors and industrial fans.
For engineers reviewing the IMC101TT038XUMA1 datasheet, IMC101TT038XUMA1 pinout, IMC101TT038XUMA1 application, or IMC101TT038XUMA1 equivalent, key selection considerations include TSSOP-38 package compatibility, IEC/UL 60730-1 Class B safety certification, sensorless or Hall-based rotor position support, and UART/analog/frequency input flexibility for speed command interface.
Technical Context
The IMC101TT038XUMA1 integrates a dedicated Motion Control Engine (MCE) executing real-time FOC algorithms at up to 96 MHz, with hardware-accelerated angle estimation, space vector PWM generation, and fault-handling sequencer - all operating independently of the user script engine. It supports both sensorless (back-EMF observer) and Hall-sensor-based commutation with configurable analog/digital Hall inputs.
Its analog subsystem includes a 12-bit ADC with multiplexer for current/voltage/temperature sensing, four programmable-gain amplifiers, and three independent analog comparators for over-current protection. The device features dual oscillators (96 MHz main, 32 kHz low-power) and internal voltage regulation for 3.3 V–5.0 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Motor Control Algorithm | Field-Oriented Control (FOC) for PMSM with built-in MCE - eliminates need for external MCU or custom firmware development. |
| PWM Outputs | 6-channel complementary PWM (3x HS + 3x LS) - directly drives external MOSFET/IGBT half-bridges without external gate driver logic. |
| Current Sensing | Single-shunt or leg-shunt topology support with integrated analog front-end - enables cost-effective, high-accuracy phase current reconstruction. |
| Safety Certification | IEC/UL 60730-1 Class B certified - meets mandatory functional safety requirements for household and industrial motor drives. |
| Operating Voltage Range | 3.3 V to 5.0 V supply - compatible with standard industrial logic rails and simplifies power domain design. |
| Package | TSSOP-38 (PG-TSSOP-38-9) - surface-mount, thermally enhanced package with 0.5 mm pitch, qualified for industrial temperature range (−40 °C to +125 °C). |
| Interface Options | UART, analog voltage, frequency, or duty-cycle inputs - allows flexible speed command integration across legacy and modern control systems. |
Pinout & Package
IMC101TT038XUMA1 is housed in a 38-pin TSSOP package (PG-TSSOP-38-9) with exposed thermal pad, optimized for motor drive PCB layouts requiring compact footprint and thermal reliability. Pin functions are software-configurable via MCE and script engine, with default assignments validated per Infineon's IMC101T-T038 pin configuration drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pins 10, 26) | Power Supply Input | Primary 3.3–5.0 V supply pins - must be decoupled locally with ≥100 nF ceramic capacitors near each pin. |
| VSS (Pins 9, 25) | Ground Reference | Dedicated ground return paths for analog and digital domains - critical for noise immunity in current sensing and PWM switching. |
| PWMUL (Pin 11) | Phase U Low-Side Gate Drive Output | Complementary PWM output driving low-side switch in U-phase leg - synchronized with PWMUH for dead-time management. |
| PWMUH (Pin 12) | Phase U High-Side Gate Drive Output | High-side PWM output for U-phase - configured with programmable dead time to prevent shoot-through in external half-bridge. |
| PWMVL (Pin 13) | Phase V Low-Side Gate Drive Output | Low-side PWM for V-phase - part of 3-phase 6-output set enabling full sinusoidal excitation of PMSM windings. |
| PWMVH (Pin 14) | Phase V High-Side Gate Drive Output | High-side PWM for V-phase - paired with PWMVL and coordinated by internal space vector PWM generator. |
Key Features
| Feature | Design Value |
|---|---|
| Motion Control Engine (MCE) | Hardware-accelerated FOC core with angle estimator and PWM sequencer - reduces host MCU dependency and ensures deterministic timing. |
| Script Engine | User-programmable application logic layer running alongside MCE - enables custom startup sequences, fault responses, and UI interactions without modifying motor control loop. |
| Integrated Analog Comparators | Three fast-response comparators with programmable hysteresis - provide hardware-level over-current protection independent of software execution. |
| Built-in Temperature Sensor | On-die thermal monitoring with ±3 °C accuracy - enables real-time junction temperature feedback for thermal derating and safe shutdown. |
| Flexible Speed Command Interface | Simultaneous support for UART, analog voltage (0–5 V), frequency (0–50 kHz), or duty-cycle inputs - simplifies integration into diverse system architectures. |
Applications
| Refrigerator Compressor Drive | Condenser Fan Motor Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMSM motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IMC101T-Q048 | QFN-48 package with enhanced thermal performance (RθJA = 35 K/W vs 52 K/W), 4 additional GPIOs, and improved ESD rating (±4 kV HBM). | Preferred for higher-power (>300 W) or space-constrained designs where thermal headroom and I/O expansion are critical. | Select when board layout allows QFN and thermal dissipation exceeds TSSOP-38 limits. |
| IMC102T-F048 | LQFP-48 with integrated boost/totem-pole PFC controller, additional analog comparator, and extended ADC channel count (12 vs 8). | Required for single-board AC-input motor drives needing active power factor correction compliant with EN 61000-3-2 Class D. | Choose only if PFC functionality is mandatory - adds complexity and cost for DC-bus-fed applications. |
Compared with IMC101T-Q048 and IMC102T-F048, the IMC101TT038XUMA1 offers optimal cost-performance balance for DC-powered, Class B-compliant PMSM drives below 250 W, leveraging mature TSSOP assembly infrastructure and minimal external component count.

FAQ
Does IMC101TT038XUMA1 require an external microcontroller to operate?
No. The IMC101TT038XUMA1 contains a self-contained Motion Control Engine (MCE) that executes FOC algorithms autonomously. An external MCU is optional - used only for system-level supervision, UI, or communication bridging (e.g., CAN-to-UART gateway). All motor control timing, current regulation, and fault response occur on-chip.
What current sensing topologies does IMC101TT038XUMA1 support?
It supports two validated configurations: single-shunt (one resistor in DC-link ground path) and leg-shunt (three resistors, one per phase leg). Both use the integrated 12-bit ADC and programmable-gain amplifiers. Single-shunt reduces BOM cost and PCB area; leg-shunt provides higher accuracy during low-speed or zero-crossing conditions.
Can IMC101TT038XUMA1 drive IGBTs directly?
Yes - its 6-channel gate drivers deliver ±1 A peak source/sink current with programmable dead time, rated for 20 V max output swing. It directly drives standard 600 V IGBTs (e.g., Infineon IKW20N60H3) and 650 V MOSFETs (e.g., IPD95R1K2P7) without external driver stages, provided external bootstrap circuitry is implemented for high-side floating supplies.
Is the script engine in IMC101TT038XUMA1 field-upgradable?
Yes. Application scripts are stored in on-chip Flash memory and can be updated in-system via UART using Infineon's iMOTION™ Development Environment (iMOTION™ IDE). Updates preserve MCE configuration and safety-critical parameters, and are verified via CRC before execution - enabling post-deployment feature enhancements and bug fixes.
